Discussion:
The circle above is plotted at the expected 59 km diameter of Carmen. With two chords we have some confidence that Dave was close to the central line of the event. There is a rotational light curve at Geneva Observatory site that indicates an elliptical shape with ratio of about 1.2. The plot below shows how this could fit to the observations.
The figures below show the light curves from two cameras that Dave was using at the same site.

Latitude -33:46:16. Altitude 110 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 20 cm Seeing Steady Clear Timing GPS - time inserted Video with frame analysis Disappearance 16:35:37.23 Reappearance 16:35:41.71 Comments: Recorded using WAT-120N+ using 16 frame (0.32 sec) integration corresponding to x5 level.

Altitude 286 m Datum WGS84 Telescope Newtonian Aperture 25 cm Seeing Slight flickering Clear Timing GPS - time inserted Video with frame analysis Disappearance 16:35:39.70 Reappearance 16:35:44.80 Comments: The main telescope was the 10" Newtonian, but I had the 8" SCT setup and running. The 8" was located aprox 10m from the 10". The event was observed with both systems but the 10: had better S/N. See light curves (attached above).
