Discussion:

The circle above is plotted at the expected diameter of Alcathous. With only one chord it is not possible to determine whether Graeme was north or south of the central line of the event, but if the diameter is accurate then he was close to the central line, which would then be south of the prediction. The circle has been plotted on the observed chord .

There is currently no light curve available for the occultation.
