High-priority objects of the Belgian Working Group Satellites
-------------------------------------------------------------

The Belgian Working Group Satellites has been active in collecting flash
period measurements since 1987. Our priority list contains over 200
satellites. An overview of our program (including recent observations) can
be obtained by sending a message with Subject: archive get program/program.*
to SeeSat-L-request@iris01.plasma.mpe-garching.mpg.de

Here is an overview of the objects which are rated 'top-priority'. These 
are objects of which we suspect that the flash period is changing in an 
atypical way. Usually this means the rocket's rotation around its own rotation
axis is accelerating, so that the flash period becomes shorter. This 
behaviour is not fully understood, so detailed observations are very much 
needed. We always welcome new observers. For more details on how to 
report/perform flash period measurements, contact me, Kurt Jonckheere or
Leo Barhorst (addresses below), or check out our Web-pages at this URL:  
http://users.skynet.be/satimage/bwgs/bwgs.htm

The following format is used :
LINE 1 : COSPAR-ID, priority code, number of observations, NORAD-number, name 
of satellite, remark on reason for top-priority.
LINE 2,3,4 : most recent observations in this format :
Date, Initials of observer, flash period in seconds, remarks about magnitude
and appearance.
