Station Map for the Occultation by (3184) Raab at Friday, 2009 March 20 (~ 01:08 UT)

V-Magnitude of target star HIP 67091: 8.5 mag
Johnson B-V Colour Index: + 1.0
Spectral Type K0
The UCAC2 gives a „pseudo-R magnitude“ of 8.3 mag

The max duration is expected to be 1.1 sec with a max drop of 8.3 mag.
The event will take place at an altitude of 46 deg and at azimuth 186 deg. The sun will be at an altitude of -37 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ± 6.77 path widths.
The probabilities to see a positive event:

Centre line: ~  6 %
Path limits: ~  6 %
1 sigma lines:  ~ 3 %
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.
