Between tracking Santa's progress, OIG seem to have latched onto Cosmos
1172, with a batch of new elsets with reasonable drag values (though I
doubt if they will allow the drag term to exceed 0.99999999).

The latest elset is:
Cosmos 1172                                      2648 x 78 km
1 11758U 80028A   97359.29021950  .97498673  48627-5  95639-3 0  2051
2 11758  61.7535 108.2494 1659945 250.0178  91.5019 12.74722052130349
showing it 6 minutes late on the "9199" evolution I posted previously.

Re-entry is now anticipated for about December 26.13 (~03h UTC +-3h).

New predictions:
