                 Flash email report for March 1995
                 ---------------------------------

Some history

The Belgian Working Group Satellites (BWGS) has been active in collecting flash
period observations of artificial satellites since 1987. All observations
are part of the PPAS database (Photometric Periods of Artificial Satellites)
which now contains over 34000 observations from more than 1200 satellites.
The Working Group publishes a monthly newsletter Flash, which is open to
contributions by observers (about any kind of satellite observations).
This email report is an addition to the newsletter. We welcome all observers
to send their flash timings to bdp@mpe.mpe-garching.mpg.de or BWGS,
