Station Map for the Occultation by (726) Joella at Tuesday, 2011 March 15 (~ 20:17 UT)

V-magnitude of target star TYC 0732-00707-1: 10.7 mag
Johnson B-V Colour Index: + 0.8
UCAC instrumental „pseudo-R“ fit-model magnitude: 10.4 mag (data from UCAC3)

The max duration is expected to be 4.2 sec with a max drop of 5.0 mag.
The event will take place at an altitude of 41 deg and at azimuth 208 deg. The sun will be at an altitude of -20 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 1.02 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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
