Station Maps for the Occultation by (1023) Thomana at Thursday, 2009 August 20 (~ 00:10 UT)
WEST and EAST
Magnitude of target star 2UCAC 31962847: 12.8 mag
The max duration is expected to be 5.0 sec with a max drop of 1.5 mag.
The event will take place at an altitude of 44 deg and at azimuth 190 deg. The sun will be at an altitude of -31 deg. (At predicted centre line for longitude E 10 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.
