2013 March 30


A Two positive observations were recorded by Paul Maley in Sumatra and Albert Lim in Singapore , using video OSD technique.

View the updated prediction.

Observers:
  1    A Lim/YK Chia,Singapore
  2    P Maley,Nikoi Is, Sumatra,Indonesia
  3(P) Predicted Centerline

        

Daphne occultation - 2013 March 30

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.

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.
