Discussion:

The circle above is plotted at the expected diameter of Notburga. The circle has been plotted to fit the observed chords as far as possible. With the high levels of integration required, and the brevity of the event, the durations must be considered approximate.

The figures below show the Tangra light curve of the occultation.

Comments: Varying cloud cover obscured observation during conduct of event such that D is clear but R is not.  
A long integration period (32 frames) required to maintain visibility of stars through cloud.
 Apparent R was 1 integration period was evident although a duration of 2 integration periods would be expected.  Reported duration of 1.3 seconds based on 1 integration period
