Discussion:

The circle above is plotted at the expected 45 km diameter of Reunerta. With only one chord it is not possible to determine whether Hristo was north or south of the central line of the event.

However, the constraint provided by Steve's observation would suggest that the chord might lie to the south of central portion of the asteroid as plotted above. Shape data at Geneva Observatory Site indicates a 0.39 magnitude variation caused by shape. This means it would just be possible to fit it into the gap between Steve's and Hristo's locations. The obesrvation will be archived with Hristo's line being the centre as this gives the least probable error.

The figures below show the light curve of the occultation as analysed by Hristo using Limovie software.

Comments: Difficult to watch as both faint but brighter while merged making it
possible, not sure that I would see the small dip in magnitude,
but feel the brightness remained constant
