Observers: 1 B Loader,Darfield,NZ 2(P) Prediction 10 July
Discussion: The circle above is plotted at the expected 22 km diameter of Annika. With only one chord it is not possible to determine whether Brian was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the close to expected chord of about 20km would suggest that the chord might lie close to the central portion of the asteroid.
The figure below shows the Limovie/Tangra light curve of the occultation.
