Station Map for the Occultation by (50) Virginia at Tuesday, 2009 January 06 (~ 21:04  UT)

V-Magnitude of target star TYC 0023-01176-1: 11.7 mag
Johnson B-V Colour Index: + 0.9
The UCAC2 gives a “pseudo-R magnitude” of 11.3 mag

The max duration is expected to be 4.8 sec with a max drop of 1.7 mag.
The event will take place at an altitude of 36 deg and at azimuth 239 deg. The sun will be at an altitude of -47 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ±  0.34 path widths.
The probabilities to see a positive event:

Centre line: ~  86 %
Path limits: ~  50 %
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.
