Discussion:

The ellipse above is plotted at the same area as the predicted 66 km circle but with the maximum axis ratio as determined by lightcurve inversion data. With only one chord it is not possible to determine whether Hristo was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the longer than expected chord of about 82 km would suggest that the chord might lie close to the central portion of the asteroid and that it observed the longest axis. The Damit 3D model view below shows the shape inferred from lightcurve inversion data.

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