The final elset for the Kupon Proton-K rocket is:
Kupon Proton-K r 151 x 148 km
1 25046U 97070B 97317.37349553 .65689875 12556-4 15941-2 0 109
2 25046 51.6160 312.6725 0002858 115.2641 244.8685 16.46147752 119
This is 1.6 seconds early against my prediction, the preceding two
elsets having been 0.08 sec and 0.01 sec early. My final SatEvo
evolution suggests that decay may have occurred near the next northbound
equator crossing at about 10:25 UTC near longitude 103 deg E.
-----------------------------
The latest elset for the C object is:
Kupon Platform? 185 x 175 km
1 25047U 97070C 97317.67996305 .02260896 12241-4 29958-3 0 111
2 25047 51.6223 310.9706 0008018 264.2780 95.7426 16.34627798 164
This is 1.8 seconds early against today's earlier SatEvo evolution.
A new analysis satisfies the equator crossing times for all today's
elsets to within 0.2 seconds and leads (again) to a decay prediction for
Saturday, November 15.5. Prediction:
Kupon Platform? 180 x 170 km
1 25047U 97070C 97318.04652788 .02915483 58090-2 31202-3 0 90110
