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 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 or Tristan Cools (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.
