Observers: 1 D Breadsell,Toowoomba, Qld, Au 2 J Bradshaw,Samford, Qld, Au 3 P Anderson, Range Observatory,Qld, AU 4(P) Prediction 26 April
Discussion:
The Elipse above is plotted at the best fit to the three observations. With three chords of very similar length we can say the the center line of the event lies approximately equidistant between David and Jonathan's sites, and roughly 30 km north of the predicted path.
The figures below shows Jonathan's Limovie graph of the lightcurve of the occultation with nice clean boundaries.

This lead to a longer PE and a slightly more inaccurate result. _______________________________ Observer Jonathan Bradshaw Location Samford, Queensland, Australia Longitude +152:52:22.7 Latitude -27:21:22.8 Altitude 95 m Datum WGS84 Telescope Dobsonian Apperture 50 cm Seeing Steady Clear Timing GPS - time inserted Video with frame analysis Disappearance 15:51:48.31 Reappearance 15:51:54.29 Comments: A perfect event, and a nice end to my drought! 20ms has been subtracted to account for camera latency - Gstar-ex @ 2x _______________________________ Observer Peter Anderson Location Taylor Range Observatory,Qld, AU Longitude +152:56:1.5 Latitude -27:27:47.6 Altitude 176 m Datum WGS84 Telescope Newtonian Aperture 41 cm Seeing Steady Clear Timing Radio broadcast - calibrated Visual, PE applied Disappearance 15:51:48.60 Reappearance 15:51:55.10 Comments: The target star was very easily 'held'. The images were steady. The events were very obvious and instantaneous to the naked eye.
