Ekard occultation__ 2016 March 4

Discussion:

Assuming that the single video frame of the image is correct, it would appear that Brian has observed a grazining occultation by (694) Ekard. With only one chord it is not possible to determine whether Brian was north or south of the central line of the event.

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