A 4 second occultation was recorded by David and Joan Dunham, using a Dobsonian Telescope and Watec 120N+ camera. A 0.5 second occultation of the faint secondary was also observed.

Discussion:

The circle above is plotted at the expected diameter of Adorea. With only one chord (for the primary) it is not possible to tell if Davis and Joan were north or south of the centre line of the event, but they appear to have been close to it. The circle has been plotted centred on the observed chords.

The event appears to have been close to the predicted path.

The figure below shows the Tangra light curve of the occultation.

Comments: Recorded with a 10in. Suitcase scope & Vaio laptop PC & IOTA timer on e. beach of New Ireland Island. Adorea was mag. 14.0. 
Joan's Limovie analysis. Attended station, distance 30 km south of the predicted central line. Joan Dunham and our driver, Joe Lavett, saw the occultation by naked eye. 
Goal was mainly to record the faint close companion, not accurate timing, with determining the size/shape of Adorea a secondary goal.
