Discussion:
The circle above is plotted at the expected 111 km diameter of Automedon. With only one chord it is not possible to determine whether John was north or south of the central line of the event.
The figure below shows the Limovie/Tangra light curve of the occultation.

Evidently, Automedon occulted the slightly brighter component of a close double. The duplicity isn't seen in GUIDE 8 or Google Sky. [and not in WDS lists. Alternatively Autoedon is much brighter than predicted. - jt]
