Kallisto occultation - 2006 November 18

Discussion:

The circle above is plotted at the expected 48km diameter of Kallisto. With only one chord it is not possible to determine whether John was north or south of the central line of the event.

The figures below show the drift-scan image of the occultation together and the data as analysed by John's Scanalyser software.
