A 12.7 second occultation was recorded by Dave Gault, using Video OSD technique.
One clearly observed miss was recorded for this event.
View the updated prediction.
Observers:
1 D Gault,Kuriwa Observatory, NSW, AU
2(M) D Herald,Murrumbateman, NSW, AU
3(P) Prediction, July 09
Discussion:
The ellipse above is plotted at the same area as the expected circle of 70 km. With only one chord it is not possible to determine whether Dave H 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 78km would suggest that the chord might lie close to the central portion of the asteroid.
The figure below shows the Aota analysis of the Tangra light curve of the occultation.
