Cloud started to obscure the field while the drift scan exposure for the
last frame was being taken, completely blanking out the end of the trail
of the occulted star. However, the occultation is visible in the first
half of the trail and timings made by careful measurement of the start
of trail, disappearance and reappearance, together with measurements of
the star trails from all three exposures to determine the effective
length of trail.
