***************************************************************************
Observations of the following objects are needed very urgently :
The following objects had a jump in Mean Motion and * MIGHT * accelerate:
21938 = 92- 20 B
The following objects had a jump in Mean Motion and ARE ACCELERATING !
21876 = 92- 8 B
The following objects had a jump in Mean Motion and HAD ACCELERATING
but there flashing period is are already going up again!
21984 = 92- 30 J

21876 = 92- 8 B
Evolution of the Flash Period of this rocket :
92- 8 B 96-10-25 17:55:18 LB 74.5 0.2 4 18.6 FF, mag 4->inv
92- 8 B 96-11-06 18:10 KJ 155.4 1.5 8 19.4 FF, 4->inv, later MM
92- 8 B 96-11-15 17:04 KJ 179.0 0.4 14 12.79
Ron Lee also saw it flashing at 96-11-18 but couldn't measure a good period
because of changing Flash behaviour of this rocket.
For the moment this object is only visible for our Southern latitude
observers. Who of them makes the next observation ?

This object is also visible for Northern latitude observers although
in the morning hours.

Thanks to the daily observations of Ron Lee, we can conclude that
the acceleration is already finished and the period is going up again.
There is no excuse (only wheather of course) not to observe this object.
It is not only visible where Ron lives... For Northern latitude it is
visible in the morning and in the evening.
Happy observing !
