(15161) 2000 FQ48 on 12 November 2020
Great Shefford was on the edge of the predicted shadow path of Minor
Planet (15161) = 2000 FQ48. The maximum duration of the occultation was
given as 3.3 seconds if observed on the central line of the shadow, but
the track must have been to the west of the prediction because a 3.5
second occultation was observed, allowing a refinement of the asteroid
size, to at least 35 km.
The faint line in the gap during the occultation is the trail of a faint
star, not the asteroid itself, which at magnitude +17.3 was too faint to
record directly on the drift-scan.
