This decaying rocket continues to be well-behaved as it heads towards
decay which I now predict for about October 31.34 or perhaps a little
later. The perigee is over the N hemisphere.

The latest elset from OIG is:
Foton N11 Soyuz-U r                              223 x 174 km
1 25007U 97060B   97302.79436704  .03029909  86048-5  66375-3 0   676

which shows it running 2.2 seconds early with respect to yesterday's
"9053" SatEvo evolution, having been 1.4 seconds late on prediction 13
hours earlier.

Here are SatEvo elsets (evolution "9062") through to decay, though I'll
update in around 24 hours.
