Station Map for the Occultation by (405) Thia at Friday, 2009 November 20 (~ 01:06 UT)

Magnitude of target star 2UCAC 38949778: 11.7 mag

The max duration is expected to be 16.8 sec with a max drop of 1.5 mag.
The event will take place at an altitude of 64 deg and at azimuth 173 deg. The sun will be at an altitude of -48 deg. (At predicted centre line for longitude E 20 deg)

There is a 1 sigma uncertainty interval of  ± 0.31 path widths.
The probabilities to see a positive event:

Centre line: ~  89 %
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.
