Station Map for the Occultation by (897) Lysistrata at Friday, 2011 June 03 (~ 23:21 UT)

V-Magnitude of target star TYC 26285-02638-1: 11.2 mag
Johnson B-V Colour Index: + 0.7
UCAC instrumental „pseudo-R“ fit-model magnitude: 10.9 mag (data from UCAC3)

The max duration is expected to be 2.6 sec with a max drop of 2.5 mag.
The event will take place at an altitude of 19 deg and at azimuth 139 deg. The sun will be at an altitude of -25 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 1.75 path widths.
The probabilities to see a positive event:

Centre line: ~ 23 %
Path limits: ~ 22 %
1 sigma lines:  ~ 10 %
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.
