hello,

91- 46 A = 21533 = Gorizont 23:
The period of this slowly drifting payload which has accelerated during 
the last years is going up since the beginning of May 1998 (detected by Jason Hatton).  
It is now visible over America.  
Who makes the next observation and confirms the slower rotation?

In our archive (PPAS) I also found that the "#02255 Pageos 1 Agena D stage (1966-056B)" is still flashing with a period of about 28 seconds.
The other fragments are not mentioned in our database, very probably
because they are too small and thus faint to be observed.
