A 1.76 second occultation was recorded by John Broughton, Reedy Creek, Australia, using the CCD drift-scan technique.
View the updated prediction.
Observers: 1 J Broughton, Reedy Creek, Australia
Discussion:
The circle above is plotted at the expected 47km diameter of Asplinda. With only one chord it is not possible to determine whether John was north or south of the central line of the event.
The figure below shows the drift-scan image of the occultation.
