Plots for four possible configurations of the event are presented below.

Discussion:

The circles above are plotted at the expected diameter of Aidamina. Without additional knowledge of the configuration of this double star, it is not possible to determine which of the above plots is correct. The circles have been plotted to fit the observed chords.

The event is clearly west of the predicted path

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