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.
