A 1.92 second occultation was recorded by John Broughton, using video OSD technique.

Jonathan Bradshaw recorded a very short and possibly spurious event.

Both events were about 40 seconds later than predicted.

Discussion:

The circle above is plotted at the expected 116 km diameter of Paris. The ellipse above is plotted at the same area as the circle.

The Observatoire de Genève database suggests a lumpy profile but not elongated enough to fit with Jonathan's spike below.

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

There was quite of lot of discussion about this set of data but I have to make a conservative decision. With only one certain chord it is not possible to determine whether John was north or south of the central line of the event and the final report shows the circle centred on John's location.

However Jonathans data is recored here should future observations be able to demonstrate the shape as as long and thin.

I have subtracted 60ms which is my estimate of the camera lag,
but the margin of error may be as high as +/- 60ms
