Station Map for the Occultation by (207) Hedda at Tuesday, 2009 January 27 (~ 04:25 UT)

V-Magnitude of target star TYC 5575-00513-1: 12.1 mag
Johnson B-V Colour Index: + 1.0
The UCAC2 gives a „pseudo-R magnitude“ of  11.6 mag

The max duration is expected to be 3.4 sec with a max drop of 2.4 mag.
The event will take place at an altitude of 27 deg and at azimuth 153 deg. The sun will be at an altitude of -32 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ±  0.54 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.
