Pompeja occultation__ 2014 August 20

Discussion:

The ellipse above is plotted at the best fit axis ratio as determined by Occult. This is slightly smaller than predicted. With two chords we can be confident of the path of Pompeja and that it was north of the predicted line.

The figure below shows Stu Parker's Tangra light curve of the occultation analysed with AOTA.
