The latest elset...

Cosmos 1172                                      5124 x 77 km
1 11758U 80028A   97357.52388302  .00997999  85496-5  15244-4 0  1926
2 11758  61.7860 111.9648 2810225 248.2235  80.2077 10.20414738130152

...shows it 96 seconds late with respect to the prediction I posted
yesterday. Not too bad, really, considering that the orbital period is
decreasing by about 80 seconds during every orbit.

My latest SatEvo evolution indicates decay at about December 26.3 and
provides the following prediction:
