A possible pair of ring events were recorded by Dave Gault et al, using an SCT Telescope and Watec 910BD camera.

One miss was recorded for this event.

There was no updated prediction for this event.

Observers:

  2    D Gault et al, Hawkesbury Heights, New South Wales, Australia      

         



       

Discussion:

The circle above is plotted at the expected diameter of Chariklo. Subsequent analysis suggests that the possible ring events are too widely separated to be valid. They must therefore be suspected to be spurious.

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