Station Map for the Occultation by (152) Atala at Monday, 2010 November 22 (~ 05:01 UT)

V-Magnitude of target star TYC 0863-00771-1: 11.7 mag
Johnson B-V Colour Index: + 0.1
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.2 mag (data from UCAC3)

The max duration is expected to be 3.0 sec with a max drop of 2.6 mag.
The event will take place at an altitude of 45 deg and at azimuth 120 deg. The sun will be at an altitude of -22 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.71 path widths.
The probabilities to see a positive event:

Centre line: ~  52 %
Path limits: ~  42 %
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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
