Greg Roberts recovered USA 129 (96072A / 24680) on 2014 Feb 03 UTC by means of a full planar search, yielding observations on two consecutive passes: http://satobs.org/seesat/Feb-2014/0024.html The solution is somewhat unstable, but I was able to fit a realistic orbit over the span of Greg's observations from Jan 27 - Feb 03: USA 129 240 X 736 km 1 24680U 96072A 14034.80266817 .00081464 00000-0 42669-3 0 00 2 24680 97.5639 90.4119 0361370 157.2331 204.5401 15.24852387 08 Arc 20140127.84-0203.86 WRMS resid 0.017 totl 0.009 xtrk I am not certain that the manoeuvre had occurred as of the Jan 27 observations. It seems probable. Further observations may lead to a more confident appraisal. Instead of the suspected reboost, we find that the perigee has been reduced by 67 km. The resulting value is somewhat below that of operational KH spacecraft.
