It was within a few seconds and on-track, when Greg and Peter observed tonight, so unless it
manoeuvres in the interim, my epoch 10255.17 elset is fine, as are any of Mike's of epoch 10255. I
also offer this update using Greg and Peter's obs:
AEHF 1 2222 X 49975 km
1 36868U 10039A 10255.88551968 .00000000 00000-0 00000-0 0 00
2 36868 18.2287 302.5108 7352003 193.5783 82.4686 1.48361180 02
Arc 20100911.09-0912.89 WRMS resid 0.009 totl 0.003 xtrk
There was a possibility of a manoeuvre later, on Sep 13, centred on 01:38:45 UTC (as I type this!);
if it occurs, and if it is similar to the last one, then the new orbit would be roughly:
2920 X 49975 km
1 70009U 10256.06857640 .00000000 00000-0 00000-0 0 09
2 70009 17.2000 301.3000 7167417 194.7000 180.8000 1.46000000 07
If it does not appear in any of the epoch 10255 elset orbits, then expect it up to several minutes
late, and off-track, possibly near the 70009 orbit.
Happy hunting!
