Eurykleia occultation - 2011 September 15

Discussion:

The circle above is plotted at the expected 85 km diameter of Eurykleia. With only one chord it is not possible to determine whether Brian was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the longer than expected chord of about 89km would suggest that the chord might lie close to the central portion of the asteroid.

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