Station Map for the Occultation by (480) Hansa at Saturday, 2009 August 15 (~ 00:22 UT)

V-Magnitude of target star TYC 1062-02240-1: 11.8 mag
Johnson B-V Colour Index: -0.1
The UCAC2 gives a „pseudo-R magnitude“ of  11.3  mag

The max duration is expected to be 5.6 sec with a max drop of  1.3 mag.
The event will take place at an altitude of 44 deg and at azimuth 235 deg. The sun will be at an altitude of -31 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.55 path widths.
The probabilities to see a positive event:

Centre line: ~  64 %
Path limits: ~  47 %
1 sigma lines:  ~ 16 %
2 sigma lines: ~ 2 %

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

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