  2(P) Prediction, 8 July                   


Aidamina occultation__ 2014 July 17


The circle above is plotted at the expected 89 km diameter of Adiamina. With only one chord it is not possible to determine whether Graeme was north or south of the central line of the event so the plot has been centered on the chord. However, assuming the updated prediction was approximately correct the almost exact maximum length of the chord would suggest that the path might lie close to the central portion of the asteroid.

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