This issue of the IAU Information Bulletin contains a minor but important modification: in this and all future IBs you will find on the inside back cover a list of the Presidents and their addresses of the eleven IAU Divisions. Hence each printed IB will now give as a quick reference the addresses of EC Members (on the inside front cover) and of the Division Presidents (on the inside back cover). The address of the Paris IAU office remains on the back page of the Bulletin.
This Bulletin also marks the halfway point in time between the XXIInd and XXIIIrd General Assemblies. Most of the preparatory work for the XXIIIrd General Assembly will have to take place during the year 1996. For this new year I would like to express to the members of our Union my very best wishes for all their scientific and private activities.

*******************************************************************************
Edith A. Mueller, General Secretary of the IAU from 1976 to 1979 and member of the IAU Executive Committee from 1973 to 1982 died from a heart attack during a holiday trip to Spain on July 24, 1995. She was 77 years old.
Edith Mueller was a truly international scientist. She was born on February 5, 1918 in Madrid, Spain, where she also started her education. She later obtained a diploma in Physics and Mathematics and (in 1943) a Ph.D. at the University of Zuerich, Switzerland. After various research positions at Zuerich, Cambridge (UK), Ann Arbor (Michigan, USA) and Basel (Switzerland) she was appointed associate professor at the University of Neuchatel before moving to Geneva, where she became a full professor in 1973. Edith Mueller also taught as a visiting professor at the Universities of Kiel (Germany) and Utrecht (The Netherlands).
Scientifically Edith Mueller is well remembered for her important work in the field of Solar and Stellar spectroscopy. Among her major results are accurate derivations of element abundances in the Solar atmosphere, which turned out to be of great cosmological significance.
Even after her retirement in 1983 Edith Mueller remained active in many national and international scientific organisations and committees. From 1979 to 1985 she served as the President of the Swiss National Committee for the IAU, from 1985 to 1988 she was the President of the IAU Commission 38 (Exchange of Astronomers).
Those who have met Edith Mueller will remember her as an eminent astronomer, teacher and organiser with an open mind and an exceptional kindness. Her colleagues and the international astronomical community will miss Edith Mueller very much.

2. EXECUTIVE COMMITTEE
2.1. 67TH MEETING OF THE IAU EXECUTIVE COMMITTEE
The 67th Meeting of the IAU EC took place on August 18-21 at Mount Stromlo
Observatory, Canberra, Australia, following the kind invitation by Prof. J. Mould,
Director of the Mount Stromlo and Siding Spring Observatories, and Prof.
D. Mathewson, Vice-President of the Union. Drs. C. Anguita and F. Pacini were
unable to attend. All other members of the EC took part in the meeting.
Among the main issues addressed at this EC meeting were:
- proposals for modifications in the Statutes, Bye-Laws and Working Rules of
the Union to formalize the IAU Divisions, to clarify the procedures for
nominating new individual members of the Union, and to improve the
procedures for proposing resolutions to the General Assemblies;
- the appointment of a new Working Group of the Executive Committee for
Future Large Scale Facilities (for details, see Section 4 of this Bulletin);
- plans considered by UNESCO and a private enterprise to produce a bright
artificial star (Star of Tolerance) by launching a large balloon satellite.
Concerning the last point the EC asked the IAU President to contact the Director
General of UNESCO and to protest against these plans on behalf of the
astronomical community.
Moreover, the EC discussed and rated the proposals for new IAU Symposia and
Colloquia. Details on the approved meetings are given in Section 5 of this
Bulletin.
2.2. 68TH MEETING OF THE IAU EXECUTIVE COMMITTEE
The 68th meeting of the IAU Executive Committee is scheduled for June 1996.
Matters to be submitted to this meeting should reach the office of the General
Secretary before April 15, 1996. As usually, matters concerning submission of
meetings must be directed to the Assistant General Secretary, for the same
deadline.
************************
3. DIVISIONS: WORLD WIDE WEB
The IAU Office is pleased to report that the Division VI (Interstellar Matter),
X (Radio Astronomy) and XI (Space and High Energy Astrophysics) have now
added their own homepages to the IAU WWW server. These new sections
provide news and announcements from the Divisions as well as basic information
on their scope and activities
************************
4. COMMISSION MATTERS
4.1. NEW EC WORKING GROUP
At its 67th Meeting in Canberra the IAU Executive Committee decided to
establish a new EC Working Group for "Future Large Scale Facilities". The
proposal for this new working group originated from the special session on this
topic at the XXIInd General Assembly in The Hague. The new Working Group
will consist of the following members appointed by the IAU Executive
Committee: H. Butcher (Chairperson), R. Ekers, B. Fort, N. Kardashev,
M. Longair, F. Pacini, L. Rodriguez, G. Swarup, Y. Tanaka, H. Tananbaum and
L. Woltjer (IAU President, ex officio).
4.2. WORKING GROUP FOR THE WORLDWIDE DEVELOPMENT
OF ASTRONOMY
Vietnam is expanding its astronomy by several university positions (research and
teaching) and an astronomy course in the last year of high school (physical
sciences branch). Since Vietnam has been very isolated astronomically, two
types of events were scheduled: a seminar on astrophysics was organized to
demonstrate the breadth of modern astronomy on October 23 and 24 in Ho Chi
Minh City, which reached mainly some 100 scientists from all over Vietnam,
gathered to view the total solar eclipse of October 24, and a course in
Astrophysics, organized at the National University of Vietnam in Hanoi on
October 30 and 31, which reached mainly some 100 physics students. Official
notice was taken of both events which were supported by France and the IAU.
5. SCIENTIFIC & EDUCATIONAL ACTIVITIES
5.1. COMMISSION 38: EXCHANGE OF ASTRONOMERS
IAU TRAVEL GRANTS: GUIDELINES
Within the limitations imposed by the budget of the Commission as approved by
the Executive Committee of the International Astronomical Union, funds are
available to Commission 38 toward grants to qualified individuals to enable them
to visit institutions abroad. It is intended, in particular, that the visitors should
have ample time and opportunity to interact with the intellectual life of the host
institution so that maximum benefit is derived by both sides. It is a specific
objective of the programme that astronomy in the home country be enriched after
the applicant returns.
1. Candidates may be faculty/staff members, post-doctoral fellows, or graduate
students at any recognised educational/research institution or observatory.
All candidates must have an excellent record of research and must have made
permanent and professional commitments to astronomy. The programme is
designed to support both the work of young astronomers and established
astronomers whose visits may benefit the country or institution visited. It is
emphasised that all recipients should return to their home institutions or home
countries upon the completion of their visits.
2. All visits must normally consist of a stay of at least 3 months at a single host
institution. In special cases, shorter visits can be considered; stopover at
other institutions en route may be permitted.
3. All visits must be formally agreed to by the Directors of the home and host
institutions involved. Such endorsements must confirm that the proposed plan
of study is a reasonable one and will be of benefit to astronomy.
4. All applicants must give details of funds currently available to her/him to
finance her/his proposed visit including supporting documents. In particular,
s/he must state what other applications s/he has submitted in efforts to obtain
support from other sources and the status of such applications. In the event
that an applicant receives funds, which may be used, in whole or in part, for
the same proposed purpose from another source, s/he is required to revise
her/his application or make a refund to the IAU. If dependants are to
accompany the applicant, details must be given.
5. The amount of the grant will be governed by the cost of one return economy
air fare and limited to the least expensive fare (such as PEX, APEX, etc.)
between home and host institutions and normally is to be used by the
applicant for such travel. With prior approval, the funds can instead be used
wholly or in part for subsistence costs during the visit.
Some grants may be awarded on the basis of a one-way fare. An example is
the case where highly qualified graduate students apply for funds to go
abroad to begin graduate studies at an institution where they have been
formally accepted.
6. Grants to attend symposia, summer schools, conferences, society meetings,
etc. are outside the scope of the programme.
Grants will not normally be made for the sole purpose of obtaining
observational data.
An individual should normally not expect to receive an IAU award for a
second visit.
7. Each recipient is required to submit a brief report to the President of
Commission 38 after her/his return from the visit. Acknowledgement of
support from the Exchange of Astronomers Programme of the IAU should be
made in any published paper resulting from the visit.
Application Procedure
1. An individual who wishes to apply for a grant under the IAU Exchange of
Astronomers Programme should read the rules carefully to ensure that the
circumstances of her/his case conform to the conditions under which IAU
grants can be made. S/he should then proceed by formally submitting her/his
request for a grant in the form of a letter to the President of
Commission 38 (see ' 4, below).
Each candidate must submit a curriculum vitae showing that s/he is
professionally qualified, and must submit a viable plan of scholarly activity to
be carried out during the visit.
The information supplied in those documents should be complete and detailed
as it will be used to judge whether the proposal is in conformity with the aims
of the programme, whether the minimum initial requirements are being met,
and whether the guidelines will permit a favourable decision. Any special
circumstances must be carefully set forth.
2. It is the applicant's responsibility to arrange for the two confidential letters of
endorsement from senior officials of the home and host institutions. These
are to be sent without delay directly to the President of Commission 38. The
letters from both institutions should confirm that the applicant's proposed visit
has the knowledge and support of the directors or senior academic/research
officers of the institutions involved. Further they should state whether the
applicant will be returning to a position at the home institution at the
conclusion of the visit. Finally, they should confirm to the President of
Commission 38 that the senior officials themselves have made every effort to
obtain the necessary travel funds from their own institutions and from other
resources within the respective countries.
The applicant must state who is responsible for her/his subsistence during the
prolonged visit at the host institute, i.e. subsistence paid by the home or by
the host institute, by a grant or fellowship or by any other means. Copies of
the relevant documents should be submitted with application. In addition the
applicant should provide information on the lowest available travel fare
required.
3. As noted above, care should be taken to make the application as complete as
possible and to include detailed statements rather than generalities. Material
should be typed and single spaced. The application will be considered as
quickly as possible, but it should be recognised that information and opinions
must be exchanged among the President, Vice-Presidents, and/or other
Members of the Organising Committee of Commission 38.
4. In summary, the application should include:
i. plan of scientific activity,
ii. curriculum vitae,
iii. letters of support from home and host institutions,
iv. information on responsibility for subsistence at the host institution,
v. information on lowest available travel fare.
and should be submitted in time for the Officers of the Commission to consult
by post.
5. All correspondence, including the endorsements referred to above, should be
directed to the President of Commission 38, International Astronomical
Union, with copy to the Vice-President. For the period August 1994-
July 1997, the addresses are:

5.2. COMMISSION 46: TEACHING OF ASTRONOMY
5.2.1. 22nd International School for Young Astronomers, Brazil
Report on the International School for Young Astronomer (ISYA)
July 9 - 29, 1995, Belo Horizonte, Brazil, by Michele Gerbaldi, Assistant
Secretary for the ISYA
This 22nd ISYA took place in Belo Horizonte, Brazil. More precisely, the first
two weeks have been held at the Federal University of Minas Gerais (UFMG) in
Belo Horizonte and the third week at the Observatory Serra Piedade, located at
some 50 kms from Belo Horizonte, at an altitude of about 1800 m. This
Observatory is run by the Astronomical Group of the ICEx (Department of
Physics).
The Brazilian sponsors were the UFMG, CNPq (Centre Nacional da Pesquisa )
and the FAPEMIG. The IAU supported travel expenses (amounting to about
USD 22 000) whereas Brazil bore the costs for hotel, meals, transportation and
meeting.
The Local Organizing Committee was chaired by Prof. Renato Las Casas
whereas Prof. Tulio Jorge dos Santos was the co-chairman. The members of the
LOC were : Rodrigo Dias Tarsia, Domingo S. de Lima Soares, Luis
Themystokliz Sanctos Mendes and Bernardo Reidel.
The foreign faculty invited were :
Dr. Craig Gullixson CCD Detectors
(National Solar Observatory, USA)
Dr. Jens Knude Interstellar Medium
(Copenhagen University Observatory, Denmark)
Dr. Reynier Peletier Galaxies
(Kaptein Astronomical Institut, Netherlands)
Dr. John Percy Teaching of Astronomy & Variables stars
(Toronto University, Canada
and President of the IAU Commission 46
"Teaching of Astronomy"
Dr. Bo Reipurt Star Formation
(ESO, Chile)
Dr. Silvia Torres Peimbert Practical Astronomy, Observations
(Observatorio Astronomico Nacional, Mexico)
Dr. Michele Gerbaldi Teaching of Astronomy and
Institut d'Astrophysique de Paris and Practical Observations
niversite de Paris Sud, France
The Brazilian faculty consisted in:
Dr. Silvia Livi, Porto Alegre University Teaching of Astronomy
Dr. Rute Trevisan, Londrina University Teaching of Astronomy
Dr. Luis Paulo Vaz, UFMG, Belo Horizonte Stellar Evolution
Two seminars were given by the Brazilian faculty of Belo Horizonte University :
Dr. Quiroga Climatic Evolution
Dr. Soares Binary Galaxies
75 applications were received out of them 17 came from East Europe countries,
India, Vietnam and Nigeria, showing the impact of previous ISYAs.
Thanks to the important financial contribution from the Brazilian authorities
obtained by Prof. Renato Las Casas, 20 foreign participants were invited (12 men
and 8 women). One participant from Mexico had to cancel his coming at the last
minute. The participants came from Argentine (3), Bolivia (1), Chile (2),
Colombia (1), Cuba (1), Mexico (1), Paraguay (2), Peru (3), Uruguay (4) and
Spain (2).
27 students participated in the school, out of them 19 were Brazilian (7 women,
12 men).
The background of the 38 participants ranged from still under-graduate students
(4) to students being preparing since about one year their Ph. D. (9). Some of
them had previous experience in teaching at high school level or had been
involved in Training the School Teachers at the University. Some of the
participants had already observed with large telescopes.
Participants gave talks on Teaching Astronomy in their country, at any level.
This gave rise to vigourous discussions on the various methods presented. Three
sessions on data reduction (Echelle spectra) were organized, using Workstations
of the Physics Department. Research talks were given. Articles provided by a
faculty member were also discussed by the participants.
Six nights were devoted to practical observations at the Observatory where two
telescopes were available: a refractor of 15 cm ( (f/15) and a reflector of 60 cm
(f/12.5).
Textbooks and reprints brought by the foreign faculty on various topics including
teaching astronomy were largely used by all the participants.
Several public talks were given by the faculty members: they were presented
either in Spanish, English or French and simultaneously translated into
Portuguese. Three talks were organized by the Amateur Astronomical Society
and given at Ouro Preto, whereas 4 talks were given at Belo Horizonte (Cultural
Center of the University).
For some students, their participation to this ISYA has definitely oriented their
future studies.
5.2.2. Teaching for Astronomy Development (TAD)
Announcements regarding TAD were sent to 30 people in 19 countries with a
finite but low level of astronomy and who might wish to enhance their astronomy.
Follow-up letters were sent to 13 people in 12 countries, noting that proposals are
due in the office of the committee secretary by January 2, 1996. The committee
is to prepare a recommendation for the IAU Executive Committee by April 15,
1996.
