Re: Decaying rocket (and fragments)

Drag rates suffered by the decaying SL-6 rocket, 97- 22 B, increased
more than expected about 24 hours ago. This caused it to run early and
brought forward the predicted decay time to about August 7.1, though
this may already be slipping back to August 7.5 or later as the
atmosphere returns to normal.

The latest elset from OIG is:
C 2342 SL-6 r1   5.0  0.0  0.0  5.5 d            233 x 186 km
1 24801U 97022B   97216.81779821  .01882831  85540-5  61044-3 0  1722
2 24801  62.7635 230.9941 0035322 118.3274 242.1427 16.23820924 13143


Of the other objects mentioned by Bjoern:

There are no further elsets for #24366. My own SatEvo evolution forced
through the final three elsest leads to decay at about August 4.2,
implying that it is already down.

#24202. Another elset today - I now expect decay about August 10.

#24395. Two more elsets released today support Bjoern's prediction of
decay early Thursday, 7th.

SatEvo predicted elsets for tonight for #24303 and #24395:
