Discussion:

The circle above is plotted at the expected diameter of Arenda. With the two chords on one line, it is not possible to determine whether Graeme was north or south of the central line of the event. The circle has been plotted on the observed chords.

The details for the star on the IOTA update do not suggest that it is double. This would indicate that Arenda may have a secondary body.

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