Genoveva occultation - 2010 June 01

Discussion:

The circle above is plotted at the expected 83 km diameter of Genoveva. With one chord and a nearby miss it is possible to to be confident that Dave was south of the central line of the event.
The remarkable thing about this event is how accurate the prediction from over a month earlier was. The center line of the circle is within a few km and less than 1 sec of the predicted time!
However an event on 2007 May 13 observed in Japan with 7 chords gave an eliptical shape of 145 x 108 km. This wouuld imply the path center was about 20 to 30 km further Northwest. There is no DAMIT model at this time to help verify the shape.

The figure below shows the Tangra light curve of the occultation.
