Observers: 1 J Broughton,Brunswick Heads, NSW,AU 2 J Bradshaw,Brisbane, QLD, AU 3(P) Prediction 3-March Three other observers registered for the event but were clouded out or failed to observe.
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.
The star is cataloged as a double with WDS entry: RA Dec Name Y1 Y2 N PA PA Sep Sep M1 M2 06076+2411POU 980 1926 1998 2 35 30 8.5 8.1 13.97 14.55 but no obvious double effects are reported and the Google Sky view does not show any hint of it being double.
