Observers: 1 W Hanna,Alice Springs, Australia 2(P) Prediction, Personal 19 June
The circle above is plotted at the expected 12 km diameter of Deimos. With only one chord it is not possible to determine whether Bill was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the chord would suggest that the it lie within a few km of the central portion of Deimos.
This was a difficult event to observe as Deimos stays very close to Mars. The images below show Deimos just before and just after occultation
The figure below shows the Tangra light curve of the occultation.
Some of the new Tangra features designed to make Jupiter moon results easier to scan helped in getting this clean result.
By the way - this is the first observed occultation by a Martian satellite. Well done Bill!
