Station Map for the Occultation by (250) Bettina at Saturday, 2009 October 31 (~ 22:13 UT)
Magnitude of target star 2UCAC 44644296: 12.5 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 12.6 mag (data from UCAC3)
The max duration is expected to be 11.2 sec with a max drop of 0.7 mag.
The event will take place at an altitude of 45 deg and at azimuth 83 deg. The sun will be at an altitude of -54 deg. (At predicted centre line for longitude E 20 deg 42 min)
There is a 1 sigma uncertainty interval of ± 0.59 path widths.
The probabilities to see a positive event:
Centre line: ~ 60 %
Path limits: ~ 45 %
1 sigma lines: ~ 16 %
2 sigma lines: ~ 2 %
(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)
PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even with a small probability.
