Station Map for the Occultation by (231) Vindobona at Sunday, 2009 January 04 (~ 04:38 UT)

Magnitude of target star 2UCAC 42194588: 11.8 mag

The max duration is expected to be 6.7 sec with a max drop of 2.7 mag..
The event will take place at an altitude of 14 deg and at azimuth 300 deg. The sun will be at an altitude of -28 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ±  0.80 path widths.
The probabilities to see a positive event:

Centre line: ~  47 %
Path limits: ~  40 %
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.
