The latest elset for the Soyuz-U rocket which launched (the real) Cosmos
2348 is:
C 2348 Soyuz-U r 306 x 159 km
1 25096U 97080B 97351.62991491 .02890368 58305-5 65010-3 0 204
2 25096 67.1440 299.3567 0110967 94.4716 266.9240 16.15309648 329
My analysis suggests decay is due at about December 21.0 with an
uncertainty of about 12 hours at present.
SatEvo predicted elsets from my "9020" evolution:

Note that perigee is close to its northern apex, improving the chances
for re-entry over the N hemisphere.
