Station Map for the Occultation by (269) Justitia at Saturday, 2009 May 09 (~ 22:24 UT)

V-Magnitude of target star TYC 4992-00231-1: 11.7 mag
Johnson B-V Colour Index: + 0.2

The max duration is expected to be 6.5 sec with a max drop of 1.0 mag.
The event will take place at an altitude of 41 deg and at azimuth 160 deg. The sun will be at an altitude of -27 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 1.74 path widths.
The probabilities to see a positive event:

Centre line: ~  23 %
Path limits: ~  22 %
1 sigma lines:  ~ 10 %
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.
