>Thanks to Stu Huston's timely advance notice, 
and OIG elsets, which I posted to SeeSat-L, I observed one of the two
objects, probably the Lewis satellite. It was 22 seconds late wrt. to
the #24909 elset (72 sec. wrt #24910) and also much closer to #24909
in track position. Shadow entry at 21:53:19 UT was 8 seconds later
than predicted by SkyMap, taking the 22 seconds in account.
Magnitude, and standard magnitude at 50% phase, about 5.0

#24883 OrbView-2 was on time, but about one magnitude fainter than before.

#24680 USA 129 was 110 sec early wrt. the Molczan/McCants elset below,
but even correcting for the early arrival, the satellite was higher in
the W than predicted. 21:38:07.5 at RA 17.42, dec.+37.46
Magn. +1, fainter in NW

#22251 was only 15 sec. late, magn. +1 in Aquarius ( SE 30 deg. )
and slighly west of predicted pos. Faint in NE
Observed 20:57:12.7 RA 22.140 dec.+19.52 (2000.0) 0.25 deg. W of predicted
         20:58:25.1    22.45      +58.24          0.1  deg. W of predicted
