Elfriede occultation - 2008 May 26

Discussion:

The Elipse above is plotted at the best fit to the three observations. With three chords of very similar length we can say the the center line of the event lies approximately equidistant between David and Jonathan's sites, and roughly 30 km north of the predicted path.

The figures below shows Jonathan's Limovie graph of the lightcurve of the occultation with nice clean boundaries.
