Ate occultation - 2010 March 28

Discussion:

The ellipse above is plotted at the same area as a circle of the expected 135 km diameter of Ate. With two chords we have good confidence that John Broughton was close to the central portion of the asteroid.

The figure below shows Jonathan's Tangra light curve of the occultation.

but no obvious double effects are reported and the
Google Sky view does not show any hint of it being double.
