Discussion:

With only one chord, it is not possible to tell if Graeme was north or sout of the centre line of the event. The misses show the event to be slightly north of the predicted path. The DAMIT model has been plotted to fit the observed chord.

The figure below shows the Tangra light curve of the occultation.
