Discussion: This was a difficult event with magnitude drop of only 0.1. The circle above is plotted at the expected 960 km diameter of Ceres. With only two nearby chords and very low probablity of shift we can be fairly certain that both observers were south of the central line of the event.

The figure below shows the Tangra light curve of the occultation from Brian.

The figure below shows the light curve of the occultation from Martin.

brightness was too small to time.
