  2(P) Prediction, TT14  27 May
    

Discussion:

The circle above is plotted at the expected 124 km diameter of Deiphobos. With only one chord it is not possible to determine whether Dave 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 134km 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.
