Duboshin occultation - 2010 April 28

Discussion:

The circle above is plotted at the expected 55 km diameter of Duboshin. With only one chord it is not possible to determine whether Dave was north or south of the central line of the event.
Note Dave Gault's two tracks are very close together in this plot.
This is the first reported successful occultation observation of Duboshin.
