Baillauda occultation__ 2014 May 22

Discussion:

The circle above is plotted at the expected 54 km diameter of Baillauda. With no positive chords we cannot say where the actual path was, so the circle has been plotted on the predicted path. Had it been on track then both John and Peter should have detected it.
