Zelinda occultation - 2013 May 12

Discussion:

The ellipse above is plotted at the best fit axis ratio as determined by Occult. The area is very close to that of the predicted circle of 123 km diameter. With 4 chords we can be confident of the path of Zelinda and that it was north of the predicted line.
