On Apr 16 I had very few successful captures, but in one shot I got a
bright flash near the start of a faint track, and after careful study
another faint track - my first successful measurement of USA 290. I also
got USA 290 in the following image, before it disappeared behind a tree.

There is a discrepancy of about 1½ s between the intervals of the first two
and the third of 43941, and the predicted times along the track. With
careful examination I cannot detect a false track start in the third, and
even less likely in the first two, since these match the exposure length.
Random error in my camera timing is more probable, since it only has 1s
time resolution.
