hello all,

Gorizont 23 = 91- 46 A = 21533
------------------------------
This evening (Mar 3) I saw Gorizont 23 again, it was flashing
with maxima of about +5.5 to +7, so a bit fainter than Sunday
morning, but still an easy target in binoculars.
I observed it between 19h22m and 20h12m UT, resulting in a
period of 50.308 +- 0.002 seconds, nearly the same as last
Sunday.  So after the acceleration which occured somewhere
between August last year and now, the period change has been
slowing down again.  Is it probably going up again ?!?

At the beginning of the observation, I saw some other flashes of
about mag +7, a little bit more South of Gorizont 23.  They were
visible for about 4 minutes becoming too faint afterwards.  This
object was flashing with a period of about 39 seconds.
At 19h25m UT it was at about RA 4h40m, Dec : -8 
Possible candidates found in Mike's geo.tle are :
- 23415 = 94- 80 A = DFH-3, seen flashing by Rainer Kracht on 95-3-25
          with a peirod of 120 seconds, mag +10 at maximum
- 23528 = 95- 13 A = Intelsat 705 which is probably still active and
          thus no flasher candidate.
Has anyone seen 23415 recently ?

regards,

don't forget to send your obs to ppas@lists.satellite.eu.org
