The final two elsets from OIG for this object were:
Cosmos 1172                                      933 x 71 km
1 11758U 80028A   97360.16530173  .99999999  42406-5  90437-3 0  2195
2 11758  61.7462 105.6440 0626938 253.7888  99.8896 15.21316347130450
Cosmos 1172                                      676 x 76 km
1 11758U 80028A   97360.23048627  .99999999  57108-5  12358-2 0  2203
2 11758  61.7455 105.4302 0444517 251.8550 104.2320 15.64002239130477

The first of these has it running 8 minutes late on the "9200" evolution
I posted here previously. The drag terms above are certainly too low by
factors of 3 to 5.

I estimate that re-entry occurred near or soon after the perigee on the
second orbit above, at about December 26.28 (~06:37 UTC).
