4(P) Prediction, 6 June
We welcome Alan as new member of the Occultation group with his first event.
Discussion:
The circle above is plotted at the expected 107 km diameter of Vanadis. With only one chord and the misses just to far to provide a constraint, it is not possible to determine whether Dave was north or south of the central line of the event.
The figure below shows Dave's Tangra light curve of the occultation.
