Discussion:

The circle above is plotted at the expected diameter of Princetonia. With only one chord it is not possible to determine whether Dean was north or south of the central line of the event. The circle has been plotted on the observed chord. The event appears to be north of the predicted path.

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