The latest elset from OIG for this object is:
Resurs-F1M Soyuz-U r 164 x 144 km
1 25060U 97072B 97324.79123129 .14581297 -12650-5 36724-3 0 192
2 25060 82.3251 250.0037 0015635 86.3747 273.9035 16.44563742 380
This shows it running 2.5 seconds early against the "9010" evolution I
posted earlier today.
A new evolution predicts decay at about November 21.06 (~01:30 UTC) with
an uncertainty of one hour or so. The evolution runs:
Resurs-F1M Soyuz-U r 158 x 140 km
1 25060U 97072B 97324.85202916 .15779152 20519+0 30461-3 0 90198

Resurs-F1M Soyuz-U r 151 x 136 km
1 25060U 97072B 97324.91277177 .20701741 38627+0 28886-3 0 90198

The final rev above takes it northbound over the central Pacific near
the dateline and then southwards to the W of Iceland (01:16 UTC), the
extreme W of Africa (01.28), the equator at 13.5 deg W (01.32),
Ascension I (01.34) and towards the far S Atlantic. My guess is that
decay will occur on the southbound leg, perhaps over Ascension.
