Antiope occultation - 2010 August 11

Discussion: The circle above is plotted at the expected 120 km diameter of Antiope. With only one chord it is not possible to determine whether John was north or south of the central line of the event.
However Antiope is in fact a binary with two similar sized components. The Miriade 3D model below shows that John's chord of about 83 km may be near to the centre of one of the components.
