Mrkos occultation - 2008 October 14

Discussion:

The circle above is plotted at the expected 30 km diameter of Mrkos. With only one chord it is not possible to determine whether Dennis was north or south of the central line of the event. However, assuming the updated prediction was approximately correct and given the constraint of a negative by Peter the plotted position is a good estimate of the path.
