Station Map for the Occultation by (318) Magdalena at Tuesday, 2009 April 14 (~ 00:51 UT)

V-Magnitude of target star TYC 0833-00754-1: 11.6 mag
Johnson B-V Colour Index: + 1.0
The UCAC2 gives a “pseudo-R magnitude” of  11.3 mag

The max duration is expected to be 28.2 sec with a max drop of 3.1 mag.
The event will take place at an altitude of 25 deg and at azimuth 255 deg. The sun will be at an altitude of -25 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.74 path widths.
The probabilities to see a positive event:

Centre line: ~  50 %
Path limits: ~  41 %
1 sigma lines:  ~ 15 %
2 sigma lines: ~ 1 %

(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)

PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even with a small probability.
