Klytaemnestra occultation - 2008 June 29

Discussion:

The circle above is plotted at the expected 77 km diameter of Klytaemnestra. With the one chord and the contraint of a sure miss by Stephen it is possible to be reasonably sure that the central path was north of both observers.

The figure below shows the Limovie lightcurve of Hristo's observation of the occultation .

Klytaemnestra occultation - 2008 June 29

Hristo notes that:"The predicted magnitude drop was 3.3m however the observed drop was a lot less. This is due to a close double star with both components of almost the same brightness"
