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.
