Sueva occultation - 2012 January 13

Discussion:

The circle above is plotted at the expected 40 km diameter of Sueva. With only one chord it is not possible to determine whether Tony was north or south of the central line of the event. However, assuming the prediction was approximately correct the close to expected chord of about 40km would suggest that the chord might lie close to the central portion of the asteroid.

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