**Station Map for the Occultation by (328) Gudrun at Saturday, 2009 November 21 (~ 17:41 UT)**

Magnitude of target star 2UCAC 23520344: 12.6 mag

UCAC instrumental „pseudo-R“ fit-model magnitude: 12.7 mag (data from UCAC3)

The max duration is expected to be 5.4 sec with a max drop of 2.2 mag.

The event will take place at an altitude of 20 deg and at azimuth 205 deg. The sun will be at an altitude of -26 deg. (At predicted centre line for latitude N 45 deg)

There is a 1 sigma uncertainty interval of ± 0.82 path widths.

The probabilities to see a positive event:

Centre line: ~ 46 %

Path limits: ~ 39 %

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.
