4(P) Prediction, TT14 28 Jan
Three other observers were registeerd but were clouded out.
Discussion:
The circle above is plotted at the expected 54 km diameter of Kallisto. With only one chord it is not possible to determine whether Dave was north or south of the central line of the event. Dave was within the 1 sigma zone about 150 km from the predicted centre so the southward shift was significant.
The figure below shows the Tangra light curve of the occultation.
