ACCELERATION REPORT : 29-01-96 
THE FOLLOWING OBJECTS ARE ACCELERATING
---------------------------------------
21015 = 90-111 B      21903  = 92- 12 B
18096 = 87- 49 B      19257  = 88- 53 B
---------------------------------------
THE FOLLOWING OBJECTS HAD A JUMP IN MEAN MOTION AND MIGHT ACCELERATE
OBSERVATIONS OF THESE OBJECTS ARE NEEDED VERY URGENTLY
--------------------------------------------------------------------
19039 = 88- 29 B       22676 = 93- 36 B
15360 = 84-109 B
(these objects had only small jumps in MM) 
-----------------------------------------

[Thanks to Mike McCants who distributed me a copy of the latest 
elementfile of Molczan, thanks to him too for all previous files]

Paul Maley wrote me that he saw the 90-111 B last week with a period
of 10.5 seconds.  So this object is probably indeed accelerating again.

Of course with "This object" I meant 92- 12 B = 21903 (sorry for any 
indistinctness)

This object accelerated in November 1995 and hasn't been observed since.
Last days its mean motion is increasing a bit faster than usual.

Mike McCants saw this object in November with a periode between 50 and 
60 seconds.  Last week I missed it two times because of bad observation
condition.  
[Don't confuse this one with 92-36 B, which accelerated a week ago and
is flashing nicely]

happy observing,
