Pegsat has but a few hours left. An elset published by OIG just minutes
ago ...

Pegsat           3.0  1.1  0.0  7.4 d            165 x 158 km
1 20546U 90028A   98317.93790787  .12108034  83530-6  74700-3 0  5445

... has it 24 seconds early with respect to the prediction I posted
yesterday, with 17 seconds of this residual arising in only the last
three orbits. My prediction for its decay time has reverted to November
14.21 (05:00 UTC +- 2h).
