The DAMIT model above is plotted at the expected size of Bettina. It appears from the length of the observed chords that Dean and Jacqui would have been close to the centre line of the event, and the DAMIT model has been plotted accordingly.
The figures below show the Tangra light curve of the occultation.

The low magnitude drop did not show up well in my recording and I initially considered it a miss.
But I have reviewed it following discussion with Dean Hooper on his nearby positive and believe I have found a real event in the noise.
