2003 AZ84 occultation - 2013 December 02

Discussion:

The circle above is plotted at the expected 727 km diameter of 2003 AZ84. With only one chord and a constraining miss we can be confident of the path of 2003 AZ84 and that it was south of the predicted line.
Sadly there is no 3D inversion model of this object available so we cannot refine the position.

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