The latest elset for this decaying Soyuz-U rocket...
Soyuz TM-27 r                                    168 x 157 km
1 25147U 98004B   98031.21285882  .10304737  12457-4  62377-3 0   129
2 25147  51.6016  18.4350 0008090  80.2928 279.9072 16.41322259   255
... shows it 13.5 seconds early against the "9007" evolution I posted
yesterday.

I now predict re-entry for today, January 31, near, or soon after, a
southbound equator crossing at 13:07 UTC at 131 deg W (over the eastern
Pacific). This is halfway around the final orbit in the following SatEvo
evolution:

Soyuz TM-27 r                                    152 x 144 km
