Discussion:
The ellipse above is plotted at the best fit for the 4 chords of Palma. It appears to have shifted about 100 km North West of the predicted path.
The ellipse shape with axis ratio of 1.18 is close to that measured by
long term lightcurve data as 1.14.
The following image tries to match the Lightcurve and Occultation shapes.
A good result with high certainty.
