  7(P) Prediction, 17 March

        

Discussion:

The circle above is plotted at the expected 49 km diameter of Garibaldi. This was a low (28%) rank prediction and there werer plenty of gaps in the picket fence and Dave was at about 1.2 Sigma position so was lucky to get an observation. With only one chord and a very nearby certain miss we can be confident of the path of Garibaldi and that it was well north of the predicted line.

The figure below shows Dave's Tangra light curve of the occultation.
