Princetonia occultation__ 20171025

Discussion:

The circle above is plotted at the expected diameter of Princetonia. With only one chord, it is not possible to tell if Jacqui was east or west of the centre line of the event. The model has been plotted centred on the observed chord.

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