Discussion:
The circle above is plotted at the expected diameter of Chariklo. The circle has been plotted to fit the observed chord.
Observations were made at the limits of the equipment used, and should be viewed with caution.
The figure below shows the Tangra light curve of the occultation.

The star disappeared from view on the video for 4 integrated frames. Poor contrast image due to 90% moon 20° from star.
Confirmation from another observation very desirable.

A light breeze made analysis difficult, but visual examination does not indicate that any occultation occurred.
