  2(P) Prediction, Personal


[mp] occultation__ 2015 June 26


The circle above is plotted at the expected 47 km diameter of Natalie. With only one chord it is not possible to determine whether Dave was north or south of the central line of the event. the circle has been plotted on the observed chord . The event is very short,and a long way from the predicted path. There are also dips of comparable depth before and after the selected one that suggest seeing was poor. so this result should be considered possibly false and not used for astrometry unless confirmed later.

The figure below shows the Tangra light curve of the occultation with time analysis by AOTA.
