Station Maps for the Occultation by (339) Dorothea at Friday, 2009 January 23 (~ 22:50 UT)

WEST and EAST

Magnitude of target star 2UCAC 35351958: 11.8 mag

The max duration is expected to be 3.7 sec with a max drop of 2.5 mag.
The event will take place at an altitude of  50 deg and at azimuth 210 deg. The sun will be at an altitude of – 60 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 1.37 path widths.
The probabilities to see a positive event:

Centre line: ~  29 %
Path limits: ~  27 %
1 sigma lines:  ~ 12 %
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.
