ACCELERATION REPORT : 28-01-96 (update)
THE FOLLOWING OBJECTS ARE ACCELERATING
--------------------------------------
21015 = 90-111 B 92-12 B = 21903
Other objects: see previous reports.
--------------------------------------
We (Mike Rosseel and I) could observe this object this evening. Its
maxima are rather broad (not so sharp as the 92-12B) and the object
sometimes has a small amplitude. We saw it with a period of about
10 seconds, so the acceleration seems to have stopped?!
Someone else has observations to confirm this?

----------------
This object is very well measurable, look at the evolution,
an accurary of 0.02 per period is possible. So this is an ideal object
for the Determination of Rotation Axis Project (DRAP). All people with
the ability to time multiple flashes should make accurate timings of all
flashes!
