Station Maps for the Occultation by (156) Xanthippe at Sunday, 2011 December 04 (~ 21:53 UT)

WEST and EAST

V-Magnitude of target star TYC 1328-00661-1: 11.5 mag
Johnson B-V Colour Index: + 0.5
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.5 mag (data from UCAC3)

The max duration is expected to be 9.4 sec with a max drop of 1.9 mag.
The event will take place at an altitude of 39 deg and at azimuth 110 deg. The sun will be at an altitude of -58 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.39 path widths.
The probabilities to see a positive event:

Centre line: ~ 80 %
Path limits: ~ 50 %
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.
