Station Map for the Occultation by (619) Triberga at Thursday, 2009 June 18 (~ 22:35 UT)

V-Magnitude of target star HIP 86320: 9.1 mag
Spectral type F5
Johnson B-V Colour Index: + 0.5
The UCAC2 gives a „pseudo-R magnitude“ of 9.0 mag

The max duration is expected to be 3.1 sec with a max drop of 4.4 mag.
The event will take place at an altitude of 43 deg and at azimuth 164 deg. The sun will be at an altitude of -21 deg. (At predicted centre line for longitude E 07 deg)

There is a 1 sigma uncertainty interval of  ± 0.65 path widths.
The probabilities to see a positive event:

Centre line: ~  56 %
Path limits: ~  44 %
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.
