Observers: 1 A Lim/YK Chia,Singapore 2 P Maley,Nikoi Is, Sumatra,Indonesia 3(P) Predicted Centerline
Discussion:
The ellipse above is plotted at the best fit axis ratio as determined by Occult. With two chords we can be confident of the path of Daphne and that it was close to the predicted line. The ISAM 3D model has been overlaid on the measured ellipse and shows reasonable fit
The figure below shows Albert's the Limovie light curve of the occultation.

Observation details for MP ( 41 ) Daphne By Star HIP HIP93026 On 2013-03-30 at 18:29:00.0 _______________________________ Observer Albert Lim Location Singapore, SG Longitude +103:46 Latitude +1:20 Altitude 48 m Datum WGS84 Telescope Refractor Aperture 11 cm Seeing Strong flickering Clear Camera Type PAL/CCIR Camera Delay 0 Timing GPS - time inserted Video with frame analysis Disappearance 18:29:00.00 Reappearance 18:29:00.00 Comments: Reanalysis by John Talbot using both Limovie and Tangra. Single or double frame dips occur at several times. These could be candidates for satellite occultations but are also consistent with scintillation noise None of these is a complete dissapearance even at field resolution, and star remains dimly visible unlike the main dip where it is absent. _______________________________ Observer Paul Maley Location P Maley,Nikoi Is, Sumatra,Indonesia Longitude 104.71011 Latitude +1.0537 Altitude 4 m Datum WGS84 Telescope Refractor Aperture 5 cm Seeing Slight flickering Thin Cloud Camera Type PAL/CCIR Camera Delay 0 Timing GPS - time inserted Video with frame analysis Disappearance 18:29:0.35 Reappearance 18:29:7.05 Comments: Special trip from USA for this event
