This occultation was recorded on video by Dave Gault in Hawkesbury Heights, NSW. As such the path must have shifted at least one path width to the north.

Observational Data:
Observer's Name : Dave Gault Aperture (cm) : 25 Focal length (cm) : 122 Type (e.g. SCT; Newtonian) : EQ Newtonian Magnification : video camera Observing site name : Dave's Skyshed Longitude (East +ve) : 150 38.4637 Latitude (South -ve) : -33 39.8663 Height above Sealevel (metres) : 286 Geodetic & Height Datums : WGS84 and MSL Sky Transparency (Delete two) : fair Star Image Stability (Delete two): fair Other Conditions: : wind, moonlight twilight, Sydney skyglow, 7.6degC Time Source (e.g. WWV, VNG) : GPS Recording method (e.g. tape) : KIWI Could you see the Asteroid? : Yes Approx. Limiting Magnitude : 13.0 | Estimated | Universal Time | Reaction | Accuracy, Remarks h m s | Time (sec) | Started Observing : 09:00 Star and Object Merged : 09:09 Disappearance At : 09:16:42.041 | 0 | 0.008 | difficult seeing Reappearance At : 09:16:49.965 | 0 | 0.008 | ditto Star and Object Separated : 09:23 Stopped Observing : 09:25 Was your PE subtracted from any of the above timings? : NA ADDITIONAL COMMENTS: The target star was at an altitude of 30 degrees placing it in the Sydney skyglow and I took ages to star hop to the star. I could not see (visually) the target star and I could only just make out the nearby mag. 10.3 star however the camera could easily reach mag 13. It was gratifying to see the asteroid appulse the star, confirming my navigation. It was even more gratifying to obtain a positive observation of duration 7.924 seconds. This would mean the path shifted at least 1 pathwidth north of the prediction.
