         INTERNATIONAL COOPERATION AND COORDINATION
                 IN VARIABLE STAR RESEARCH


The first European meeting of the American Association of Variable Star
Observers (AAVSO) will be held in Brussels, Belgium, from July 24 to July 28,
1990. The conference will be dedicated to the topic of worldwide cooperation
and collaboration between variable star observers.

Variable star photometry plays a vital role in collaborative multi-wavelength
and multi-site ground-based and space programs. The purpose of the meeting is
to bring together observers from around the world to review results of
collaborative programmes, to define scientific Key Projects, and to promote and
initiate collaborations between several teams. All presentations will be
published in a Proceedings Volume.

This announcement both serves as an invitation to attend, and as a call for
papers. For more information, please contact one of the undersigned.
