Station Map for the Occultation by (2847) Parvati at Friday, 2011 May 27 (~ 23:40 UT)

V-Magnitude of target star TYC 5781-00823-1: 10.2 mag
Johnson B-V Colour Index: + 0.8
UCAC instrumental „pseudo-R“ fit-model magnitude: 10.0 mag (data from UCAC3)

The max duration is expected to be 1.0 sec with a max drop of 5.8 mag.
The event will take place at an altitude of 17 deg and at azimuth 122 deg. The sun will be at an altitude of -27 deg. (At predicted centre line for longitude E 25 deg)

There is a 1 sigma uncertainty interval of  ± 4.07 path widths.
The probabilities to see a positive event:

Centre line: ~  10 %
Path limits: ~  10 %
1 sigma lines:  ~ 5 %
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.
