After a very hot day (32C and no wind) the night was pleasant cool at 24C.
At first clear skies, later some scattered thin clouds and some haze.
Towards dawn more thin and later thicker clouds.

24841 97 030F was R + flare
28538 05 004B was F with P ~ 10 sec. in 1st pass,
29393 06 037A was R with P ~ 3 sec,

11731 80 019C was perhaps imaged.
Residuals:
11731 80 019C   | -0.35520 deg  -21.595 sec 639.8 day, 668.7 km
But with almost 2 year old elements it seems unlikely it was only 21 sec
late.
Checking with Satfit as UNID 16736B gives the following candidates:
11732  -61.299    6.116    0.025 16736B  667.113
11731   -0.998   -0.078    0.019 16736B  639.837
So it looks like 11731 was indeed imaged.

Several satellites have higher residuals; see below.
