I found USA 129 again today Apr.11 at 19:50:14.7 UT RA 07:15 Dec.+17.5 (1950)

This indicates an unexpected MM change of .03, much smaller than the big
change due, but much much larger than the small corrections previously used
to synchronise two Keyholes.

My observation is also more consistent with an apogee kick, than with
the perigee kick ususally done.

Here is an approximate orbit under these assumptions:

USA 129 apogee kick Apr.8 15:00 UT ??
1 24680U 96072  A 98098.57250336  .00015000  00000-0  21865-3 0    36
2 24680  97.8430 159.4788 0490822  63.4607 301.6056 14.80426366  4146

This time I did not see a flare in the S, but in the NW, at about
19:49:00 UT, around mag. 0
