Station Map for the Occultation by (17) Thetis at Sunday, 2011 June 05 (~ 21:09 UT)

V-Magnitude of target star TYC 0844-00483-1: 11.3 mag
Johnson B-V Colour Index: + 0.4
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.2 mag (data from UCAC3)

The max duration is expected to be 3.8 sec with a max drop of 1.7 mag.
The event will take place at an altitude of 36 deg and at azimuth 255 deg. The sun will be at an altitude of -14 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.5 path widths.
The probabilities to see a positive event:

Centre line: ~ 68 %
Path limits: ~ 48 %
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.
Let other observers know about you observing plans: Announce your station with OccultWatcher !
