Vanadis occultation - 2012 June 23

Discussion:

The circle above is plotted at the expected 107 km diameter of Vanadis. With only one chord and the misses just to far to provide a constraint, it is not possible to determine whether Dave was north or south of the central line of the event.

The figure below shows Dave's Tangra light curve of the occultation.
