The IC 418 Campaign in 1993 (DSN 10)

In December, 1993, a photometric multisite campaign was undertaken in order to investigate the fascinating variable central star HD 35914 of the Planetary Nebula IC 418. 5 observatories were involved, 120 hours of data were obtained by a variety of techniques. HD 35914 exhibits irregular and cyclic light variations with a time scale of days and 6.5 hours respectively. A discussion of those variations can be found in the referred paper below.
