The latest OIG elset for this is
Foton N11 Soyuz-U r                              202 x 164 km
1 25007U 97060B   97303.59156211  .03910335  87111-5  50809-3 0   722
2 25007  62.7835 155.8120 0029116 115.2601 245.1444 16.33679774  3352
which shows it running 5.3 seconds late against the "9062" evolution I
posted yesterday.

Predicted elsets (my evolution "9068") to decay:
Foton N11 Soyuz-U r                              186 x 159 km

I now predict decay at about October 31.41, perhaps near the southbound
equator crossing at 143 deg E at 09:56 UTC though the uncertainty is
still at least one orbit. The final rev above takes it over Europe (in
daylight) along a track from Gibraltar (09:23) to Berlin (09:28) and St
Petersburg (09:31), onwards over Siberia, N China and to the S of Japan
(09:51), across the equator and Papua New Guinea, E of Australia and
over the South Island of New Zealand (10:09).
