View the Linoccult prediction.
Observers: 1 H Pavlov,St Clair, NSW, Australia 2(P) Prediction Linoccult 13 August
Discussion:
The circle above is plotted at the expected 42 km diameter of Bihoro. Note the Predicted path is right up in the top left corner at the maximum zoom in Occult Plot. 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 45 km would suggest that the chord might lie close to the central portion of the asteroid.
The figure below shows the Tangra light curve of the occultation.
