Leonteus occultation - 2010 November 27

Discussion:

The circle above is plotted at the expected 86 km diameter of Leonteus.

With no positive chords we cannot say where the actual path was, so the circle has been plotted on the predicted path. Sadly our network is too spread to catch all events even on a clear night.

Paul's before and after frames are shown below. These are a good illustration of how a positive occultation can give much better position accuaracy than interpolation astrometry which made it look as if that was a definte hit.
