The latest elset for this decaying rocket is:
C 2349 Soyuz r                                   225 x 177 km
1 25168U 98009B   98050.65709893  .02671205  40323-5  66033-3 0   135
2 25168  70.3840 342.6122 0036151  65.9881 294.4958 16.26906732   361

This has it only 0.9 second early against the "9006" SatEvo evolution I
posted here yesterday, though it had been as much as 6 seconds earlier
on an intermediate rev.

My latest evolution leads to decay at about February 21.3 +-0.3day and
provides the following predicted elsets:
