Acceleration Overview : Feb 15, 1997

The following list gives an overview of some of the top-priority
objects of the Belgian Working Group Satellites.
Most of these rockets seem to have an acceleration of their rotation,
in other words : a decrease of the flash periods.

For each satellite you find a number of observations in the format:
date-observer-flash period-remarks.  This list is generated from
the PPAS, our database of flashing periods.

Timings of the Flashing Periods of these objects are very much
appreciated.  We need regular observations !

At the end of the mail you'll find elements for these satellites.

Happy observing !

The period has been going down linear with about 0.09 seconds a day at the
beginning.  During the last week the decrease of the period slowed down
to about 0.05 seconds a day.  Probably the minimum will be reached
soon.  We still need to continue to observe this object regularly.
