Station Map for the Occultation by (747) Winchester at Monday, 2010 August 30 (~ 03:13 UT)

Magnitude of target star 2UCAC 34798981: 13.1 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 13.9 mag (data from UCAC3)

The max duration is expected to be 5.2 sec with a max drop of 0.39 mag.
The event will take place at an altitude of  26 deg and at azimuth 103 deg. The sun will be at an altitude of -19 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.81 path widths.
The probabilities to see a positive event:

Centre line: ~  46 %
Path limits: ~  39 %
1 sigma lines:  ~ 15 %
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.
