Station Map for the Occultation by (169) Zelia at Monday, 2009 April 13 (~ 02:32 UT)

Magnitude of target star 2UCAC 27848332: 11.8 mag

The max duration is expected to be 2.8 sec with a max drop of 1.3 mag.
The event will take place at an altitude of 19 deg and at azimuth 230 deg. The sun will be at an altitude of -23 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 1.00 path widths.
The probabilities to see a positive event:

Centre line: ~  38 %
Path limits: ~  34 %
1 sigma lines:  ~ 14 %
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.
