Aralia occultation - 2001 May 09

Discussion:

The circle above is plotted at the expected 51 km diameter of Aralia. With two such close chords it is not possible to determine whether they were was north or south of the central line of the event. However, The approximately 47 km chord is close to the expected maximum chord of about 51 km and this would suggest that the chords might lie close to the central portion of the asteroid.

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