Nothwithstanding these conditions, I managed to image the Keyhole USA 129 (96-072A) again, plus the Iranian rocket booster Safir 2 r/b (09-004B) that launched OMID in February. I imaged it earlier in the morning of 7 March.
At that time, it showed bright flares in a slow pattern. It is still doing so, as yesterday evening's images show. The time between the bright glints is slightly less than it was early this month. I determined a 31.7 second interval between two of the glints, with glint times at (March 29 UTC):
On March 7, the determined glint interval was 33.25 seconds.
Below are the two images of last evening, plus the brightness curves. The glints appear to be slightly asymetric, with a slightly more shallow fall-off of the brightness after the glint maximum:
