  3(P) Prediction,  18 May


    

Discussion:

The ellipse above is plotted at the maximum axis ratio as determined by lightcurve inversion data and with an area the same as the predicted diameter of 168 km. With two chords we can be confident of the path of Prokne and that it was slightly south of the predicted line.

The figure below shows Steve's Limovie light curve of the occultation.

The figure below shows Hristo's Tangra light curve of the occultation.
