Final elset (38 seconds early on yesterday's prediction):
APStar 1 CZ-3 r 276 x 122 km
1 23186U 94043B 99159.03524062 .69572668 -98345-5 12384-2 0 7087
2 23186 26.5576 95.8273 0117073 301.3547 57.8559 16.27565814 68434
Note: This probably decayed one orbit earlier than I predicted, close
to perigee. I think is just possible, though, that it survived for up
to one more orbit, hence the +-90m uncertainty in my estimate.
