Gorizon 23 = 91- 46 A = 21533  was last observed by Ron Lee, 
already two weeks ago.
91-046 A 98-01-07 02:10      RGL 2547.9 0.5  50 50.96 

The period of this object is going down slowly.  During the last
months it has been going down faster (about 0.011 s/D) than before
(when it was about 0.007 s/D).
Gorizon is at about geostationary distance, but drifting to the West
at about 5 degrees per day.

As it was over America two weeks ago, it is now observable from
Australia and Asia.  
How will the period have changed ??  Who makes the next observation,
(Vince or others) ?

On Jan 19, Russell Eberst saw 81- 33 B = 12389 = Cosmos 1263 C1 rocket
during two consecutive passes with a period of about 11 seconds.

During 1997, it was seen Steady several times, so it has/is very probably
accelerated.  Who confirms ?

-----
Who has tried Superbird over Europe during the last weeks ?

Observations of the flashing period of these (and other) objects are
appreciated very much !
