OIG has released two further elsets for the decaying Cosmos 2342 SL-6
rocket:
C 2342 SL-6 r1   5.0  0.0  0.0  5.5 d            200 x 171 km
1 24801U 97022B   97218.66086564  .03323991  87245-5  51990-3 0  1814

C 2342 SL-6 r1   5.0  0.0  0.0  5.5 d            195 x 169 km
1 24801U 97022B   97218.84446873  .03701953  87438-5  50533-3 0  1822
2 24801  62.7629 222.6828 0020095 120.6763 239.6399 16.34037366 13475

These show it 2.0  and 3.7 seconds early with respect to my "9174"
evolution, posted earlier this (UK) evening. My new estimate for decay
is August 7.84 (about 20:10 UTC) but the uncertainty is still a couple
of orbits.

Updated predictions through to decay:
