The activities of the IAU form a sort of tidal-wave pattern, with highs at the General Assemblies and lows midway between. Thus, this Information Bulletin appears at what should be "low ebb". In fact, there has been no noticeable decrease in the workload of the Secretariat, but the direction of the flow is changing perceptibly: With the Highlights and Transactions volumes from the last GA off to print, and a first Web page and meeting proposal forms for the next GA now in place, the outgoing tide from Kyoto is over and the incoming tide for Manchester picking up.

With a Secretariat staff of only two, those individuals are crucial for the work of the Union in general and the General Secretary in particular. We are fortunate that, with almost no gap since the departure of Julie Saucedo on June 30, we have been able to recruit a very capable successor, Jodi Greenberg. Jodi is from the USA, but has lived for long periods in South America, mostly Ecuador and Colombia, as well as in Ukraine, Hungary, and France before settling in Paris. She has integrated very quickly into our little team and, with her excellent language skills, is handling a large part of our contacts with Members. Many readers will already have been in touch with her, as she has put a major effort into the membership data base upgrade that Julie started before her departure (please check the list of still-incomplete member addresses in Sect. 13.3!).

The Executive Committee meeting here in Paris in July was a very productive one. A brief summary of decisions is given in Sect. 5, and much of the rest of the contents of this IB concerns the follow-up of these decisions. The rich programme of approved IAU scientific meetings in 1999 is listed in Sect. 6, and the newly-revised Working Rules in Sect. 9. The EC discussed and recognised the need for the IAU to take a more visible stand on significant issues of public concern, and steps are now being taken to set up a procedure for the future selection, preparation, and dissemination of IAU Press Releases. As examples of the visible expression of the concerns of the IAU on matters of current importance, the two Policy Statements issued by the EC are printed in Sect. 7 and 8 of this IB. As public documents, they are also available from our Web site and may be freely quoted provided credit is given to the IAU.

News on the preparation of the 24th General Assembly, August 7-19, 2000, is found in Sect. 3 and maintained at the IAU Web site (NB: Only our new URL www.iau.org will be active after the end of 1998!). We look forward to receive a large number of proposals for exciting scientific events in Manchester. These will keep the EC and the Secretariat busy between now and IB 84, which will contain much more information on GA 24. I note that also the organisers of GA 25 in Sydney are already making preparations for another memorable event there in 2003.

Finally, the very best wishes of the IAU Officers and Secretariat to all readers for a happy and rewarding 1999!

November 13, 1998

Johannes Andersen

General Secretary



Fortunately, the second half of 1998 has been somewhat less exciting in terms of disruptions of our work by unexpected outside events in the astronomical and personal spheres: No asteroids, no staff departures, no accidents, etc.! We did spend far more time than expected on a computer upgrade after yet another disk crash of our previous laptop PCs, as well as on a capricious piece of software called Windows NT. However, at the time of writing, all is working fine in the skilled hands of Monique Léger-Orine and Jodi Greenberg. All this, unfortunately, caused delays in the preparation of Highlights of Astronomy Vol. 11 and Transactions XXIIIB, recording our scientific and other business in Kyoto. However, with the strong help of three spirited Copenhagen students, the Highlights (two volumes totalling 1200 pages!) went to press in August and should be out before the end of 1998. Also the Transactions (another 750 pages) are now in the hands of Kluwer and should be out shortly after you receive this IB. As this is the last IAU volume to be produced by Kluwer in their 30-year period as IAU Publisher, I take the opportunity to thank them for their collaboration over all these years, and to welcome the ASP, the IAU Publishers for the next six years

Much work has been put into consolidating our records of all kinds. Jodi Greenberg has been busy cross-checking, updating, and rationalising the data base of our current members (see address update request in Sect. 13.3). One result should be an updated On-Line Directory on the Web by the time you read this. Our apologies to members who find that we have been far too slow in doing this, but we have more tasks than we have hands! With outside help, we are also building up a data base of all IAU members, starting at the first General Assembly in 1922 and ending today; this will help us answer the many questions we receive about the membership of individual astronomers. Our archives for 1919 have been stored at the Académie des Sciences here in Paris (see Sect. 10 for details). Near-complete lists of past IAU publications have been prepared and posted on the Web. The Secretariat has a complete set of the Transactions, Reports on Astronomy, Highlights of Astronomy, and Symposium volumes, but our set of Colloquium proceedings is still very incomplete. We will identify the missing volumes in the Web list and hope that readers can help.

Our Web page is continually updated and expanded in response to arising needs. New features are the page on Frequently Asked Questions (yes, buying star names and dangerous asteroids are among them!), and the Policy Statements also printed in this IB. As a further means for the IAU to communicate effectively with the public and the media, Commission 6 has prepared a proposal for the preparation and dissemination of IAU Press Releases in the future. The idea is not to compete in the flood of daily news, but to have the voice of the IAU heard on issues of major concern to astronomers and/or the public. An IAU PR Committee will ensure that topics are of appropriate significance for an IAU PR, that the scientific facts have been properly verified, and that the form of presentation will be suitable with regard to its expected public impact. An IAU PR Office will ensure a professional presentation before final release by the General Secretary. The proposal will now be reviewed by the Executive Committee, and the final implementation will be reported in the next IB.

To conclude on a more exotic note, your GS visited Uzbekistan in October at the occasion of the 1200th anniversary of the famous medieval astronomer Al-Farghani. The visit gave a striking impression of the splendors of the past as well as the difficulties of the present. I hope that the IAU may be able to play a constructive role for the future of astronomy also in this region of the world, and trust that the visit will prove helpful in this endeavour.

As preparations for the XXIVth General Assembly August 7-19, 2000, in Manchester, UK, are ramping up, a preliminary information page has been set up at the IAU Web site with links to meeting proposal guidelines and forms, in particular. Up-to-date information will be provided through this page, including a link to the GA Web site itself when available. The Local Organising Committee reports on the further preparations as follows:

The Local Organizing Committee is moving ahead with arrangements for the XXIVth General Assembly to be held in Manchester, UK during the period 7-19 August 2000. Members will be interested to learn that Manchester International Airport's second runway will be commissioned on this timescale, thereby increasing its capacity to 20 million passengers per year. Many of you will be able to fly directly into Manchester. Others will make use of the Channel Tunnel which is increasingly popular with travellers from Europe. Much information about travel arrangements will be provided in due course.

World Event Management has been contracted to undertake the registration and accommodation booking management for the General Assembly. Arrangements will be in place for electronic as well as paper registration and payment. Accommodation reservations have been secured, including ample provisions of low-cost rooms.

A sub-committee of the LOC is working on an interesting and varied programme of vistits during the General Assembly for participants and accompanying persons. Historic and scenic sites abound, ranging from the Wordsworth houses in the Lake District to Chatsworth House (the Cavendish family home) in the Pennines. Opportunities will also be available to view the well-known radio telescopes at Jodrell Bank.

An experienced Editor has been chosen for the daily newspaper of the General Assembly. This is a vital organ of communication during the meeting and has been an indispensable feature of recent General Assemblies.

You are encouraged to put the date 7-19 August 2000 into your diaries. The Preliminary Announcement of details of arrangements for the General Assembly will be in Information Bulletin 85, to be published 1 October 1999. May 1, 2000 will be the deadline for Early Registration. The scientific programme will be decided by the IAU Executive Committee, including the accompanying symposia (see announcement and deadlines in Sect.6 of this IB).



An increasing number of Division and Commissions have set up Web pages, as noted below. Links to all of these are provided from the IAU and Divisional Web pages as appropriate.

Division II: Sun and Heliosphere (Peter Foukal)

A recent poll of the Division II OC Members indicates general satisfaction with the current make-up of our division, so no changes are being contemplated.

Some members have suggested that a solar nomenclature sub-committee would be useful. Suggestions are welcome (also volunteers).

The Division sponsors or co-sponsors IAU Symposium 195 on "Highly Energetic Physical Processes and Mechanisms for Emission from Astrophysical Plasmas" in Bozeman, Montana, July 6-10, and Colloquium 179 on "Cyclical Evolution of Solar Magnetic Fields" in Kodaikanal, India, December 13-16 (abstract deadline March 1, 1999). Contact information on these meetings is given in Sect. 6 of this IB and maintained up-to-date at the IAU web site.

It is time to start thinking about ideas for Div II-related symposia or colloquia for the year 2000. To optimize coordination at the Division level, it would be desirable to send drafts of your proposals by mid-February 1999, to the Division President at pfoukal@world.std.com.

Our Working Group on Eclipses is trying to coordinate efforts to observe next year's event in Europe and Asia. Their website is www.williams.edu/Astronomy/IAU_eclipses; you may also contact jay.m.pasachoff@williams.edu.

Inputs to enrich our Division (or Commission) web-sites are welcome! If you have ideas for the Divisional web-site, kindly contact P. Foukal at the e-mail address above. Inputs for the Comm 12 and Comm 49 sites should be sent to: jmariska@aspen.nrl.navy.mil, and to frank.verheest@rug.ac.be respectively. Inputs for an eventual Comm 10 web-site should be sent to aigx@sun10.bao.ac.cn, with a copy to benz@astro.phys.ethz.ch.

Finally, Division II notes that the Editorship of the Quarterly Bulletin on Solar Activity (QBSA) has passed from Dr. P. Lantos (Paris) to Dr. K. Shibasaki (Nobeyama, Japan).

Division III: Planetary Systems Sciences (Michael A'Hearn)

The Executive Committee has agreed that the full name of Division III be modified as above to reflect a deliberate emphasis at the creation of the Division which was lost at a later time.

Dr. F. Colomb has resigned as President of Commission 51 (Bioastronomy) due to pressure of other activities. Division III regrets the fact that his other duties prevented him from continuing in office. The Vice President of Commission 51, Dr. Bowyer, is now the Acting President of the commission. Commission 51 also has a newly available web page at URL sag-www.ssl.berkeley.edu/IAUCom51/.

Commissions 20 and 21 have also established web pages recently: Comm. 20: (Positions and Motions of Minor Planets, Comets, and Satellites) is at www.astro.uu.se/IAU/c20, while Comm. 21 (Light of the Night Sky) is at sag-www.ssl.berkeley.edu/IAUCom21/. All Commission web pages are linked from the Divisional and IAU web pages.

The Small Bodies Names Committee (SBNC, a divisional working group) has published its working guidelines for assigning names to comets. They are available through the committee's web page: www.ss.astro.umd.edu/IAU/sbnc/. The SBNC emphasizes that all names are actually decided on a case by case basis and that the guidelines are just that, not rigid rules. The SBNC tries to achieve fairness to all individuals involved and simplicity in the naming - the guidelines being a means to that end.

Division IV: Stars (Lawrence Cram)

Division IV has established a Web page with links to all Commissions, Working Groups and WG Newsletters associated with the Division, at URL www.astrop.physics.usyd.edu.au/IAU. Web sites for Commissions 35 and 36 have also been set up and linked from this page.

Division IX: Optical and Infrared Techniques (Chris Sterken)

The Executive Committee has approved that the name of the Division be modified as above, to better reflect the range of scientific activities covered by the Division.

Division XI: Space and High Energy Astrophysics (Willem Wamsteker)

During the past six months many things have happened in the area of the Division which are considered to be of interest, not only to the members of the Division, but also for the astronomical community as a whole. We will try in these reports to keep you abreast of the developments of interest to all astronomers. We try to collect all relevant information. Since it is the first time that we do this, I would appreciate feedback on the contents of this report, which is not guaranteed to be complete. I thank Drs. Giovanni Fazio, Vincente Domingo and Hajime Inoue for information included below. (Any inaccuracies in the listing below are the full responsibility of the Division President).

Space Astrophysics News

SOHO recovered

On 24 June 1998, after completing its nominal two-year mission, ground controllers lost contact with the Solar and Heliospheric Observatory, which went into a spin around its principal axis of inertia. On 3 August, contact was re-established, and on 16 September, Sun pointing was achieved. By 23 October, 10 out of the 12 instruments on board had been tested and were found to be working nominally again, a great accomplishment by the SOHO recovery team. Further information: sohowww.estec.esa.nl/operations/Recovery/

ROSAT in-orbit problems

This X-ray satellite, in orbit since 1997, suffered a startracker failure on 28 April 1998. During the testing of the reconfigured spacecraft, a suspected sun-pointing caused significant damage to the instruments. As a consequence the deadline for the 9th AO has been delayed indefinitely. Further information: heasarc.gsfc.nasa.gov/docs/rosat/rosgof.html

DEEP SPACE 1 launched

NASA's DS1 mission was successfully launched from Cape Canaveral and will fly by the near-Earth asteroid 1992 KD on 28 July 1999, with the possibility of an extended mission to the dormant comet Wilson-Harrington in January 2001 and comet Borrelly in September 2001. Further information: nmp.jpl.nasa.gov/ds1/

The 71st Meeting of the Executive Committee

The 71st meeting of the EC took place in the Council Room of Observatoire de Paris, France, on July 3 and 4, 1998, at the invitation of Vice-President Catherine Cesarsky. From the many topics discussed and decisions taken, the following highlights are mentioned here:

On administrative matters, the EC approved a set of draft Statutes and By-Laws, revised to clarify the procedure for admitting several countries represented by a single Adhering Body (see IB 81, p. 45) and to reflect the reorganization of ICSU (IB 82, p.13). These will be submitted to the next General Assembly for decision. New Working Rules were approved by the EC (reproduced in Sect. 9 of this IB), including a simple provision for Members to resign from the Union if they so wish, and an explicit procedure for Resolutions proposed by Working Groups. Decisions on national membership are reported in Sect. 13 of this IB.

The IAU was found to be in good financial health, the normal GA-year deficit in 1997 being actually some 20% smaller than budgeted. Grant income from ICSU/UNESCO shows a declining trend from the forecast in the approved 1998-2000 Budget, a trend that is expected to continue. The EC discussed possibilities for modifying the IAU's traditionally conservative investment policy, but decided to await the introduction of the Euro before considering major changes (later events seem to confirm the wisdom of this decision!). The Finance Sub-Committee is providing continuing advice and oversight on the Union's financial affairs.

On matters related to the Divisions and Commissions, the EC approved a change of the name of Division IX to Optical and Infrared Techniques, to better reflect the true activities of the Division. The EC also approved the proposal to appoint an Acting President of Commission 50 (see Sect. 4 above). (Subsequently, the EC has also agreed that Division III be named Planetary Systems Sciences, a correction of an earlier mistake). The communications between Division Presidents (DP) and the EC was discussed at length. The direct personal interaction at the Kyoto EC meetings was felt by all to have been very fruitful, but the cost of inviting the DPs to all EC meetings was considered to be prohibitive. As an interim measure, the present strong involvement of the DPs in the selection of the scientific meeting programme for 1999 would be further strengthened and optimised in collaboration between DPs and AGS. DPs already receive copies of the Agendas for EC and Officers' meetings and are invited to comment or propose additional items.

The EC received a Final Report on the 23rd General Assembly and reiterated its thanks to the organisers. Preparations for the 24th GA are proceeding smoothly (see Sect. 3 of this IB).

The approved programme of scientific meetings in 1999 is listed in Section 6 of this IB. The joint IAU-COSPAR-UN Educational Workshop, to be held at the UNISPACE III conference in 1999 is part of our initiative to join forces with sister organisations to achieve a more effective use of our scarce manpower and external funding. The joint IAU-UN Environmental Symposium (Symp. 196), also at UNISPACE III, is part of our strategy for obtaining a form of international protection of the night sky, following up on Resolution A1 of the Kyoto GA (IB 81, p. 27, and IB 82, p. 2). The EC approved the action plans of the GS in these areas.

In addition to these meetings, the EC approved the 24th International School for Young Astronomers (ISYA), to be held in Romania in 1999, and the 25th ISYA to be held in Thailand in 2001. The EC also approved an increased activity level for the TAD programme in Central America and exploratory activities in Morocco (see Sect. 11).

The EC recognised an increasing need for effective communication with the public and the media on matters of international concern. The EC therefore requested that Commission 6 (Astronomical Telegrams) prepare a set of guidelines and procedures for such an IAU service. As examples of subjects that would be suitable for public announcements, the EC issued two IAU Policy Statements on Environmental Challenges to Astronomy and Research on Near Earth Objects (NEOs). The text of these statements is reproduced as Sect. 7 and 8 of this IB. Recognising the key role of the IAU, through its Minor Planet Center (MPC), in maintaining the international character of and coordination in NEO research, the EC approved the reinstatement of its previous financial support for the MPC, at a significantly increased level.

The 72nd Meeting of the Executive Committee

The 72nd EC meeting will take place at Universidad de Chile, Santiago, Chile, June 18-20, 1999. Items for the Agenda should reach the General Secretary before May 1, 1999. 1 "The 72nd EC meeting will take place at Universidad de Chile, Santiago, Chile, June 18-20, 1999.

Issued by the IAU Executive Committee on July 4, 1998

During the 20th century, astronomy has made great progress on the most fundamental questions concerning the origin and evolution of the Universe and our place in it. Within subjects ranging from the origin and evolution of the Solar system, the formation and evolution of stars and the origin of the chemical elements, the nature and evolution of galaxies, up to the structure, origin, and evolution of the Universe itself, sound physical theories have been developed and tested against a wealth of increasingly detailed observational facts.

Except in the Solar system, astronomers cannot conduct experiments on the subjects of their studies. Thus, our understanding of the Universe is primarily based on observations of the electromagnetic and other kinds of radiation emitted by stars and galaxies. The dramatic recent progress is due to a series of observational breakthroughs, made with ground and space based observatories and closely linked to the development of cutting-edge technologies. In order to probe the diverse range of astronomical objects, observations must cover all wavelengths from radio via infrared and optical to X- and gamma-rays, some of which are only accessible from space.

The phenomena thus discovered include the most violent events known in the Universe. Yet, these objects are so far away that the signals recorded by astronomical telescopes when capturing radiation from the early phases of the Universe are vastly fainter than those familiar from everyday life. This fact makes astronomy especially vulnerable to, but also a very sensitive indicator of, environmental degradation affecting the night sky at all wavelengths.

At the threshold of the third millennium, progress in the further exploration of the depths of the universe is threatened by human activities affecting the night sky. Briefly, these adverse effects are fourfold:

1: Pollution by scattered light from ground based light sources.

To millions of people living in or near great cities or industrial centres, the sight of the dark night sky is unknown. Plainly visible from space, this light not only obliterates the faint signals reaching us from the Universe, it also represents the useless waste of much fossil or nuclear fuel. Thus, economic incentive and scientific interest go hand in hand in this matter. Simple measures exist to direct light where it is needed, and thus both conserve energy and keep the night sky pristine; they need to be implemented more widely. The IAU values and supports the numerous national and local initiatives taken to promote understanding and action on this issue.

2: Interference from man-made radio noise.

Radio astronomy has contributed several of the most fundamental discoveries of the past century. Now, however, it is under relentless and increasing pressure, above all from the communications industry, to give up the protected wavebands containing the astrophysically most important frequencies. Considering that an ordinary portable telephone, if placed on the Moon, would be one of the very brightest sources in the radio sky at its wavelength, even sideband radiation from transmissions in a permitted waveband may be fatal to astronomy. Continued efforts by the IAU and URSI (Union de Radio Science Internationale), as represented by the Inter-Union Committee on the Allocation of Frequencies for Radio Astronomy and Space Science (IUCAF) within the International Telecommunications Union (ITU), are vital for radio astronomy to survive in the face of this competition.

3: Space debris.

Space debris from spacecraft and launchers has two kinds of deleterious effects on astronomy: First, it leaves luminous trails on the sky which ruin astronomical observations. Second, direct hits by spacecraft debris are a threat to the survival of scientific satellite observatories, including the International Space Station, somewhat analogous to the effects of swarms of small natural meteorites. The former effect is mainly felt by astronomers; the latter problem affects all satellites regardless of their purpose. For this reason, international efforts are under way to control the growth of space debris, which will hopefully also benefit astronomy.

4: Technology experiments and artistic or commercial displays in space.

Experiments continue to be proposed which would place strongly luminous objects in space, whether for technology assessment (generation and transmission of illumination or power), or for artistic or commercial purposes. Responsibly executed and carefully controlled experiments should, of course be allowed, but malfunctions may occur. Moreover, at the moment, no international regulations exist to prevent uncontrolled private and other enterprises from launching objects into space that would ruin the night sky for people of all nations, potentially for many generations: Unlike ground-based art or advertising displays, space displays respect no national sovereignty or environmental regulations. An international treaty is needed to prevent unbridled proliferation of such displays to the irreparable detriment of scientific progress in astronomy.

The IAU, therefore, urgently appeals to the nations of the world to negotiate and implement an international treaty regulating space activities that would unnecessarily endanger what is perhaps the last natural resource available to all mankind: The night sky. Clearly, nations should be free to develop potentially beneficial space technology in a controlled and responsible manner as defined by internationally recognised guidelines. The IAU urges, however, that such guidelines be defined with due regard to the protection of peaceful scientific investigation, following the models set by, e.g. the Antarctic Treaty or the international agreements on radio frequency allocations.



Issued by the IAU Executive Committee on July 4, 1998

The Solar system contains a large number of bodies ranging in size from the major planets to tiny meteorites. Research over the last several decades has revealed that all major bodies of the Solar system have suffered larger or smaller impacts of bodies ranging in size from millimetres to kilometres, the best-known example of which is the abundance of craters on the Moon. Geological features on Earth show that impacts of significant size have occurred also on our own planet. The realization that such impacts occur at long, but presently poorly-known intervals has recently caused growing concern in the public, and in the press.

Research on the minor constituents of the Solar system - the minor planets or asteroids - has formed part of astronomical research for the last two centuries. The International Astronomical Union (IAU) has acted as the international focal point for this research since the foundation of the Union in 1919, in particular through its Commission on the Positions and Motions of Minor Planets, Planets, and Satellites. As part of this function, the IAU has for over 50 years operated a Minor Planet Center (MPC), currently at the Smithsonian Astrophysical Observatory (SAO; Cambridge, Mass., USA), for the collection of data and the dissemination of information concerning minor planets and, lately, comets. When continued research showed that the orbits of several minor planets crossed that of the Earth, the IAU in 1991 appointed a Working Group on Near Earth Objects (NEO) to coordinate international studies of NEOs and develop suitable strategies for detection, follow-up, and orbit prediction. As one result of this work, the international Spaceguard Foundation was formed, and a number of observational programs for the detection of NEO's have been started. The WGNEO is also active in the development of proven algorithms for long-term NEO orbit prediction and thus for assessing the distance to which NEOs may approach Earth within the next few centuries.

Currently, the number, size distribution, and orbits of individual NEOs are incompletely known from observation. Thus, the most urgent task is the detection and observation of NEO's to determine their orbits. This is an international responsibility that requires the efforts of and support for astronomers around the world. As the international organization of professional astronomers, the IAU coordinates this activity through the NEO Working Group and offers the services of the MPC for the collection and collation of new observations and computation of predictions from which follow-up observations can be made to improve our knowledge of the orbits and sizes of these objects.

It is possible that, sometime in the future, these studies may lead to the prediction of an actual impact on Earth. In such a case, this information must be promptly conveyed to the governments of the world, who may be in a position to organise countermeasures (a subject outside the mandate of the IAU). On the other hand, public announcements of potential impacts without proper verification are clearly undesirable. The IAU has therefore charged the WGNEO, in consultation with astronomers worldwide, to draft a set of recommended procedures to be followed in case minor planets and comets are discovered that lead to predictions by the MPC of potential impacts. These procedures will conform to the following general principles:

1: All information will be openly shared with astronomers and the general public world-wide.

2: The content of public statements that might alarm the public will be subject to prior scientific peer review by the IAU.

3: The IAU Officers and appropriate authorities will be consulted before such information is released to the press.

The IAU reaffirms and increases its support of the Minor Planet Center, as the international clearing-house for this research, and acknowledges the support of SAO and NASA for its operation. The IAU encourages all countries of the world to contribute to the effort of charting the NEO population and will continue to ensure that this global issue is addressed in a properly international forum.



Working Rules


1.   The International Astronomical Union follows the regulations of ICSU: The International Council for Science (and concurs with ICSU statute 5 which defines the basic tenets of non-discrimination and of the universality of science:

"In pursuing its objectives in respect of the rights and responsibilities of scientists, ICSU, as an international non-governmental body, shall observe and actively uphold the principle of the universality of science. This principle entails freedom of association, expression, information, communication and movement in connection with international scientific activities, without any discrimination on the basis of such factors as citizenship, religion, creed, political stance, ethnic origin, race, colour, language, age or sex. ICSU shall recognise and respect the independence of the internal science policies of its National Members. ICSU shall not permit any of its activities to be disturbed by statements or actions of a political nature."

Participants in IAU-sponsored activities who feel that they have been subjected to discrimination are urged in the first instance to seek immediate clarification of all aspects of the incident, which may have occurred simply because of misunderstandings due to cultural differences inherent in an international organization such as the IAU. If the attempt to seek clarification does not prove satisfactory, contact should then be made with the IAU General Secretary who will seek to resolve the issue.

In the last resort, the Chairperson or the Secretary of the ICSU Standing Committee on the Freedom in

the Conduct of Science (SCFCS) should be approached. The SCFCS has been created by ICSU in 1963 in order to safeguard the principle of the universality of science and to assist in the solution of specific problems. The SCFCS has, ever since, worked vigorously to ensure that this principle is upheld by providing advice and taking appropriate measures. The Executive Secretary of the SCFCS, Dr. P. Schindler, can be reached at the Swiss Academy of Sciences, B�renplatz 2, 3011 Bern, Switzerland (Telephone: 41 31 312 33 75, Telefax: 41 31 312 32 91, e-mail: schindler@sanw.unibe.ch).

Working Groups established by Divisions and Commissions have to be approved by the Executive Committee. All Working Groups are established initially for a period of three years. Before each General Assembly the Divisions and Commissions shall inform the Executive Committee which Working Groups are to be retained for the next 3-year period and which Working Groups are to be dissolved.


10. THE IAU ARCHIVES 1919-1970

The preservation of the Archives of the Union is one of the responsibilities of the General Secretary. As previously mentioned, we are fortunate that former IAU President Prof. Adriaan Blaauw, has undertaken, and now completed, the sorting, selection, packing and inventory of our archives for the period 1919-1970.

By agreement with the French Académie des Sciences, the IAU achives have been deposited in the Archives of the Académie where they will be preserved and administrated to fully professional standards, a task that would be impossible for our Secretariat to undertake. All access to the IAU archives will require the prior written authorisation of the IAU General Secretary. Requests for access to the IAU archives, including a description of the scientific project for which they will be used, should be addresses to the General Secretary well in advance of the projected visit. The IAU expects to receive a copy of all publications or reports including material from its archives.

Prof. Blaauw has prepared a detailed Inventory of the IAU archives, indicating the existence and precise location of the archival material. The Inventory (approx. 60 pages) will be printed in a limited number of copies, available upon request to the IAU Secretariat. The Inventory will also be made available from the IAU Web page, under Administrative Matters.

An integral part of the Archives is a collection of the IAU Transactions for the period, which is, however, unfortunately not complete. The missing Volumes are Nos. I (1922), V (1935), and XIIIA (1967). There is also a collection of all General Assembly Newspapers which have appeared since such newspapers were initiated in 1958, except that the whole set from the GA in Buenos Aires (1991) is missing. We should be very grateful to readers who might be able to provide these missing volumes and newspapers.



The primary educational activities of the IAU are the exchange programme operated by Commission 38 (see below), the International Schools for Young Astronomers (ISYA), and the Teaching for Astronomy Development (TAD) programmes organised by Commission 46. Partial support for these activities from ICSU and UNESCO is gratefully acknowledged.

With the approval of the COSPAR Bureau, consultations are held to define a collaboration on future joint IAU-COSPAR educational initiatives that would profit from the synergy between the capabilities of the two organisations. As a step in this process, a joint IAU-COSPAR-UN Special Educational Workshop will be held during the UNISPACE III conference in Vienna in July 1999 (see Sect. 6 for details).

11.1. Commission 38: Exchange of Astronomers

Within the budget approved by the Executive Committee, Commission 38 allocates grants to qualified individuals to enable them to visit institutions abroad. It is intended, in particular, that the visitors should have ample opportunity to interact with the intellectual life of the host institution so that maximum benefit is derived by both sides. Another specific objective is that astronomy in the home country should be enriched after the applicant returns.

Detailed guidelines for these grants and the application procedures to be followed were published in IB 81 (pp. 37-39) and are available from the Commission 38 Web page (linked from the IAU home page). All correspondence related to the programme should be directed to the President of IAU Commission 38, with a copy to the Vice-President. For the current triennium, their addresses are:

11.2.2 Teaching for Astronomy Development (TAD): Progress Report

Vietnam: Ten of the university astronomy teachers who attended last year's IAU-sponsored "Summer school on astrophysics" met at a workshop in Vinh City, Sep. 21-24, with Donat G. Wentzel and James C. White II (both USA) as foreign advisors and with senior Vietnamese astronomers observing. The teachers have enthusiastically changed the style and to some degree the content of their teaching, aided by the texts that were donated by Saunders College Publishing last year. This year's practical exercise for the teachers was based on the color photos and computer-based data on variable stars that are part of the AAVSO's educational package "Hands-On-Astrophysics". A new university text is in preparation, both in English and Vietnamese, with the IAU contributing the extra cost of quality photographs. Vietnam's first (Japanese-donated) public planetarium has opened in Vinh. The IAU will help establish a program for the city schools. A variety of educational materials has been sent to several universities. The recent arrival at several universities of slide projectors, modern PC's, and limited e-mail will help accelerate progress.

Central America:

The second observing course at the Central American Observatory in Honduras, 15 Jan. to 15 Feb. 1998, served eight students from the six participating countries, most continuing from the previous course. Maria Cristina Pineda de Carias (Director of the Observatory) supervised a program of acquisition and reduction of photometric data on variable stars (0.4m telescope with IAU-supplied CCD photometer). Michael Barylak (ESA, Spain, travel supported by ESA) emphasized stellar spectra and the capability to use computer/internet based catalogues of data from ground and space.

The fourth Central American Course on Astronomy took place in Panama 15 Feb. to 1 March 1998, in connection with the solar eclipse on 26 Feb. Forty participants included Julieta Fierro and Armando Arellano Ferro (both Mexico); delegates from the six countries of the Central American Assembly of Astronomers; and 25 local physics teachers and students. Three teams observed the eclipse successfully. The lecture program has led to discussions how to make future meetings more effective for astronomy in Central America.

Armando Arellano Ferro (Mexico) taught a special course on astronomy in El Salvador, 22 Sep. to 10 Oct., emphasizing both practical work with a small telescope (their 0.3 m telescope and the IAU Traveling Telescope photometer) and the corresponding radiation physics and astrophysics. Participants are both University of El Salvador science and engineering students and members of the Asociacion Salvadoreña de Astronomía.

Morocco: The National Committee on Accreditation has approved a program of research and teaching of astronomy within the physics department of University Hassan II in Casablanca. Work towards the initiation of a TAD programme in Morocco is in progress.

ICSU: A major concern of the General Secretary (GS) has been to strengthen liaisons with our main international partner organizations. Developments at ICSU were described in IB 82 (p. 13), and we are collaborating with ICSU on the plans for the UNESCO/ICSU World Conference on Science in Budapest in June 1999.

Developments at ICSU were described in IB 82 (p. 13), and we are collaborating with ICSU on the plans for the UNESCO/ICSU World Conference on Science in Budapest in June 1999.

COSPAR: Our long-standing good relations to COSPAR are being strengthened in our collaboration on the organization of two meetings (on environmental and educational matters) at UNISPACE III in 1999, and constructive discussions on more long-term joint initiatives in the educational field are under way. The COSPAR Executive Director, Prof. S. Grzedzielski, has provided the following short report on the 32nd COSPAR Scientific Assembly:

The Assembly, in Nagoya (Japan), July 1998, broke all records with more than 2500 papers accepted for 80+ symposia and scientific meetings. The attendance was second largest ever with over 1700 scientists registered. The meeting was extremely well organized by the Japanese hosts.

COSPAR Assemblies strive at covering the full spectrum of space research disciplines (cf. the COSPAR publications.) Astronomy in the broad sense of the term was discussed at more than twenty symposia and other meetings. As usual, a prominent place was occupied by solar system exploration with emphasis on remote and in situ studies of small bodies and, in the case of planets, on the results of the current Galileo mission to the Jovian system, as well as present and future exploration of Mars. Other well covered topics were solar physics and solar activity, which were discussed at six different symposia devoted to subjects from helioseismology to heliospheric physics to solar-type activity observed in other stars. High-energy astrophysics was represented by symposia on broad band X-ray spectra, active galactic nuclei and cosmic rays. As COSPAR draws most of its input from novel techniques of observation from space, due attention was devoted to such developments as space infrared telescopes and space VLBI. Search for new experimental techniques was also most prominent at the symposium on fundamental physics where possibilities of testing general relativity, equivalence principle, etc. were discussed.

Three new members were elected to the COSPAR Bureau 1998-2002, including the current IAU General Secretary.

United Nations: The IAU has Observer status with the UN Committee on the Peaceful Uses of Outer Space in Vienna, which has been instrumental in preparing the major UN treaties and conventions regarding outer space. Former IAU GS Derek McNally has been very effective in raising awareness of the environmental dangers to astronomy there. Our efforts are now directed at collecting support for an agreement to regulate the launch of strongly luminous and radio-emitting satellites, so science may remain alive in parallel with technical and commercial developments. The UN Office of Outer Space Affairs also has a long record of educational initiatives in astronomy in developing countries. We are seeking ways to develop this synergy to make everybody's efforts more effective: Bright young scientists need not only brains and training (e.g. through an ISYA), but also a job and appropriate tools to use their capabilities effectively in the service of their country. Collaboration between pure and applied sciences, and with governments, should help to reach this goal.



13.1 National Membership

At its 71st meeting the Executive Committee considered an application by the Macedonian Academy of Sciences and Arts for full membership in the IAU and found it to be in order. Based upon the authorization of the XXIIIrd General Assembly, the EC decided to welcome the Former Yugoslavian Republic Of Macedonia as a Full Member of the IAU. The Union looks forward to collaborating with our Macedonian colleagues for the benefit of astronomy in the country.

Following five years of non-payment of dues, and after several attempts to arrive at a solution to this problem, the EC regretted to note that the membership of Azerbaijan had terminated at the end of 1997, pursuant to Article 7 of the IAU statutes.

Proceedings of IAU General Assemblies and Symposia are published as a series by the IAU Publisher, i.e. by Kluwer for all meetings through 1997 and by the Astronomical Society of the Pacific for all meetings from 1998 onwards. Publishers for Proceedings of IAU Colloquia, Regional Meetings, and Co-Sponsored Meetings are chosen by the organisers.

Lists of previous IAU meetings and their proceedings are maintained at the IAU Web site under Scientific Meetings and IAU Publications. Please report any errors or omissions to the Secretariat. Especially, our information on some early Colloquia is still incomplete, and we would appreciate any additional information that may enable us to complete it. Moreover, while the Secretariat has a complete set of Symposium volumes, our collection of Colloquium proceedings is seriously incomplete. The missing volumes will be identified in the list posted on the Web, and we shall be most grateful to readers for any donations of missing books.

The Highlights of Astronomy, Vol 11A+B and IAU Transactions Vol. XXIIIB are now in print; the former should appear by the end of 1998.

16.1 The Grave of Walter Baade to be Preserved by his Home City

Following an appeal from German and international astronomers, including IAU President R.P. Kraft, the President of the Astronomische Gesellschaft, Prof. W. Pfau, informs us that the city of Bad Salzuflen has agreed to take responsibility for the preservation of the grave of Walter Baade, who has left no living descendants. The IAU shares the appreciation of our German colleagues that the resting-place of this eminent astronomer will thus be preserved as a "Prominent Person's Grave" by his home city.

16.2 UTC Time Step

The International Earth Rotation Service (IERS) announces a time step at the end of 1998. At midnight, the second marker 23h 59m 59s of 1998 December 31 will be followed by 23h 59m 60s (same date), then by 0h 0m 0s of January 1, 1999. The difference TAI-UTC will then increase from +31s to +32s.

16.1. The International Geophysical Calendar 1999

The Secretariat has received the International Geophysical Calendar for 1999. This Calendar is issued under the auspices of the International Space Environment Service (ISES) of the International Council for Science (ICSU). Observations for solar phenomena and the International Solar Cycle Studies 1998-2002 project are covered in this calendar.

The Calendar, with basic explanations, has in the past often been printed in the Information Bulletin. Given the large volume of the present issue, we give here instead the Web addresses where the complete Calendar and all explanatory files can be found and downloaded:

www.ngdc.noaa.gov (Solar and Upper Atmosphere icon under Get Data), and
