Here we go again :-)
Last night's launch of Astra 1G by a Proton-K from Baikonur left the
usual couple of objects in decaying LEO. The latest elsets are:
Astra 1G Proton-K r 213 x 160 km
1 25072U 97076B 97337.57063482 .02444920 12156-4 30777-3 0 58
2 25072 51.6019 65.3741 0040109 271.0544 88.5991 16.32311616 104
Astra 1G Proton platform 183 x 159 km
1 25073U 97076C 97337.57070584 .16517139 12367-4 13888-2 0 44
2 25073 51.5865 65.3536 0018362 274.0050 86.1667 16.38074930 99
I've guessed the identities myself, but I'm more confident than I was
with the Kupon launch about which is the rocket and which the
"platform".
The latter object has probably already decayed at about December 3.78
(18:48 UTC) according to a SatEvo evolution through the published
elsets. My final predicted elset is:
Astra 1G Proton platform 139 x 131 km
1 25073U 97076C 97337.75310350 .97084139 10923+2 80883-3 0 90042
2 25073 51.5829 64.3167 0006583 274.7813 85.1435 16.51662190 126
An evolution of the rocket suggests decay at about December 5.2.
Predicted elsets from my "9005" evolution:
Astra 1G Proton-K r 207 x 158 km
1 25072U 97076B 97337.81538244 .03165611 61369-2 34879-3 0 90050
