I may be mad for tackling this, but the Inflatable Antenna (#23872 = 96-
32 C) appears to be heading for decay at about May 22.38 by my SatEvo
analysis.
The latest OIG element is:
IAP
1 23872U 96032C 96142.61791612 .04923902 64422-1 81640-2 0 111

My predicted elements (based on above with "improved" n and ndot):
IAP
1 23872U 96032C 96143.05136238 .16604553 14904+0 94965-2 0 90119

---------------------------------------------
OIG's latest OIG element for object #11791 = 80- 32 B (Atlas F R) is:
80- 32 B
1 11791U 80032B 96142.18163644 +.06322808 +83244-5 +15730-3 0 05357

This is 4.4s late with respect to the predicted orbit evolution I
posted yesterday.
I now expect decay at about May 22.77 and predict the following
elements meantime:
80- 32 B
1 11791U 80032B 96143.04601349 .08886394 14004-1 17231-3 0 95350
