Note: The final elset has this running 24 sec late against the
prediction I posted a few hours before. In my opinion, at least one
of the final four published elsets is bad - my suspicion falls
on the penultimate elset (above) which indicates a too-low drag
and has the object about 8 seconds later than expected at that time.
My estimated elset for the beginning of the final rev is:
Cosmos 2377 Soyuz r 134 x 105 km
1 26776U 01022B 01153.81334655 .78820339 46473+1 27666-3 0 90329
2 26776 67.0951 128.5745 0022171 94.5353 265.7179 16.57466700 663
I put the decay southbound near northern Vietnam following a pass
across China. The orbit might have continued across Malaysia,
Indonesia and Western Australia.
