Observers: 1 H Pavlov,St Clair, NSW, Australia 2(P) Prediction, Linoccult
The circle above is plotted at the expected 34 km diameter of Gretia. With only one chord it is not possible to determine whether Hristo was north or south of the central line of the event.
The figure below shows the Tangra light curve of the occultation.
This result must be qualified as marginal as there are only 2 sample periods in the dip and several other noise spikes of similar sixe.
