Discussion:

The circle above is plotted at the expected diameter of Lehigh. With only one chord, it is not possible to tell if Dave was north or south of the centre line of the event. The circle has been plotted centred on the observed chord. The event appears to have been to the south of the predicted path.

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