Discussion:

With only one chord it is not possible to determine whether Dean was north or south of the central line of the event. However, assuming the updated prediction was approximately correct the chord of about 60km would suggest that the chord might lie close to the central portion of the asteroid, expected diameter 75km.

The figure below shows the Tangra light curve of the occultation with AOTA analysis.
