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.
