Note: The latest elset shows this running 103 sec early against

revs runs is:
GPS 2-20 r2 3.0 1.5 0.0 6.5 d 2.9 231 x 121 km

I put decay near the end of this final predicted orbit, close to a
northbound equator crossing over the Atlantic to the NE of Brazil.
One or more further elsets may yet appear.

Final decay analyses:
Source Prediction made Predicted decay at Latitude Longitude
UTC UTC deg deg
SpaceCom Jan 12 09:32 Jan 12 07:33 +-30m 29.9 S 71.7 E
SatEvo Jan 12 19:45 Jan 12 07:41 +-40m 12.6 N 63.5 E
Final elset:
Zeya r 3.0 0.0 0.0 6.0 d 3.7 129 x 125 km
1 24745U 97010B 01012.19736915 .20993328 27472-5 12537-3 0 9235

Note: The final elset shows this running 40 sec late against yesterday's
prediction. This definitely lasted longer than I expected. I suspect
that it decayed northbound over the Arabian Sea (NE Indian Ocean) on the
following SatEvo-predicted orbit:
Zeya r 3.0 0.0 0.0 6.0 d 3.7 122 x 119 km
1 24745U 97010B 01012.25779860 .30061881 11897+1 13069-3 0 99238
2 24745 97.1549 292.0701 0002222 233.4664 126.5132 16.57230330217602
Earlier in that orbit it would have passed southbound over N America
from the middle of Hudson Bay at 06:40 UTC to Minneapolis at 06:44
and Houston at 06:47. the next rev would have carried it southwards
from Calgary at 08:09 to Los Angeles at 08:13.
