The latest elset for the C object, the cylinder, is:
Telstar 5 deb 153 x 149 km
1 24814U 97026C 97147.03626963 .34190949 12555-4 91515-3 0 228
2 24814 51.5668 133.6877 0003514 271.1508 88.9187 16.45625401 380
This is 9 seconds early against the evolution I posted yesterday. It may
have decayed on this rev or it might have survived to another equator
crossing as my final SatEvo analysis implies:
Telstar 5 deb 123 x 122 km
1 24814U 97026C 97147.09684193 4.40468363 50000+2 18622-2 0 90187
2 24814 51.5722 133.3382 0000230 216.6470 143.3513 16.56486590 399
but perhaps not much further. Indeed, if it decayed on this latter rev
it might have done so along a track roughly from Los Angeles (02.:30
UTC) to the Twin Cities (02:36 UTC). My guess, however, is for decay at
about May 27.10 UTC, a little before landfall on the W Coast. (This is a
cue for USSPACECOM to prove me wrong.)

The latest from OIG for the rocket is:
Telstar 5 Proton r 208 x 197 km
1 24813U 97026B 97147.40832680 .01328667 12024-4 38926-3 0 179
2 24813 51.5901 131.6629 0008173 289.9634 70.0484 16.26438849 441
My latest evolution indicates decay at about May 31.5 and provides the
following prediction:
Telstar 5 Proton r 203 x 193 km
1 24813U 97026B 97148.02247333 .01320577 10304-2 33953-3 0 90176
2 24813 51.5897 128.2514 0007529 292.5166 67.4036 16.27854801 549
Telstar 5 Proton r 200 x 191 km
1 24813U 97026B 97148.45202780 .01470280 13120-2 33897-3 0 90173
2 24813 51.5893 125.8607 0007043 294.3060 65.6204 16.29051041 617
Telstar 5 Proton r 195 x 186 km
1 24813U 97026B 97149.00381574 .01730761 18902-2 33813-3 0 90178
2 24813 51.5888 122.7831 0006366 296.6095 63.3252 16.30808571 704
