hello all,
I will finish the next update to the PPAS in the next days and
already want to focus on the following two objects :
Gorizont 23 = 91- 46 A = 21533
------------------------------
Observations of the last months : flashing period
91- 46 A 97-12-16 17:58:06.8 KJ 0.2 46 51.220 T=2356.1s, mag +5,later+8
91- 46 A 97-12-27 02:46 RGL 1.0 40 51.10 T=2044.1, ssm 1/4 period
91- 46 A 98-01-05 03:56:11.6 RM 306.2 0.5 6 51.04
91- 46 A 98-01-07 02:10 RGL 0.5 50 50.96 T=2547.9
91- 46 A 98-01-25 12:42 AB 0.2 30 50.667 T=1520.0, +-0.002
91- 46 A 98-01-26 12:45 AB 0.2 25 50.652 T=1266.3, +-0.002
91- 46 A 98-02-17 19:46:25.3 KJ 0.1 38 50.289 T=1911.0, mag max+5
91- 46 A 98-02-26 19:05 JPH 501.4 0.2 10 50.14
91- 46 A 98-03-18 MM 49.93
This one has been accelerating linearly during Jan and Feb, but seems
to be slowing down now.
Very often it is around mag +5.5.
Gorizont 23 is almost geostationary and is visible over Europe in the
next two weeks. Who makes the next observation ?
ETS 6 = 23230U = 94056A

Observations of last months : flashing period
94- 56 A 97-12-27 05:16:41.2 RE 50
94- 56 A 98-01-02 04:53:31.5 RE 25
94- 56 A 98-03-08 11:22 RGL 241.1 1.0 24 10.05 ssm
94- 56 A 98-04-08 12:31 AB 975.8 0.1 50 19.516
94- 56 A 98-04-14 12:06 AB 193.7 .04 10 19.374 +-.004, flsh peak mag +2
94- 56 A 98-04-16 12:30 AB 966.9 50 19.338 P=19.3380+-.0004,mag+2.7
94- 56 A 98-04-17 11:15 AB 19.313 P=19.3125+-.0005,mag+2
94- 56 A 98-04-22 21:20 KJ 76.7 0.3 4 19.2 clouds+tree, mag+10
This on is in a high eccentric orbit (didn't made it to geostationary)
and is also rotating faster around his primary body axis. Sometimes
it is giving very bright flashes.
