Discussion:

The circle above is plotted at the expected 109 km diameter of Aegina. With only one chord it is not possible to determine whether Stephen was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the match to the maximum expected chord it would suggest that the chord might lie close to the central portion of the asteroid.

The figures below shows the light curve of the occultation as analysed by Limovie software.
