#11268 = 79- 12 A = Cosmos 1077
SpaceCom has still to post its final analysis for this. Current
estimates for the decay are:
SpaceCom: Jun 26 15:37 +-2h 73.9 N 95.6 E
SatEvo: Jun 26 15:01 +-45m 54.8 S 56.2 E
What is probably the final elset...
Cosmos 1077 5.0 1.5 0.0 5.4 v 13 148 x 132 km
1 11268U 79012A 00178.51410082 .21056467 -98639-6 23404-3 0 6440
2 11268 81.1364 211.2586 0012554 263.1232 97.0557 16.49804762176503
... shows this running 20 sec early against yesterday's SatEvo
prediction. I show the decay occurring northbound over the SW Indian
Ocean. My predicted elset for the final rev:
Cosmos 1077 5.0 1.5 0.0 5.4 v 13 132 x 121 km
1 11268U 79012A 00178.57462304 .55246173 24262+1 31351-3 0 96445
2 11268 81.1347 211.1723 0008787 262.8762 97.0239 16.54868405176511

(Very similar) final decay analyses:
SpaceCom: Jun 26 05:01 +-43m 3.9 S 75.7 W
SatEvo: Jun 26 05:00 +-1h 0.0 72.9 W
Final elsets:
Express 3A Proton r 150 x 145 km

Yesterday's decay prediction had an uncertainty of +-3h and not the +-9h
reported at the time. Against that prediction, the penultimate elset
shows it running only 0.8 sec early. The latest elset, however, has it
4.7 sec late, but is suspect with a too-high eccentricity. I prefer the
following elset for the final rev...
Express 3A Proton r 127 x 125 km
1 26379U 00031B 00178.14768560 .35975698 14864+1 18446-3 0 90186
2 26379 51.6169 276.9924 0002155 326.3557 33.6306 16.55095369 358
... with decay near the northbound equator crossing at the end of this
orbit, over Colombia, S America. If it survived, it would have passed
just E of Caracas, Venezuela, at 05:03 UTC, over S England (in daylight)
at 05:19 and onwards across Europe to Kiev, Ukraine, at 05:24.
