Station Map for the Occultation by (405) Thia at Sunday, 2009 November 29 (~ 04:46 UT)

V-Magnitude of target star TYC 1336-01533-1: 11.1 mag
Johnson B-V Colour Index: + 0.5
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.4 mag (data from UCAC3)

The max duration is expected to be 12.4sec with a max drop of 1.7 mag.
The event will take place at an altitude of 53 deg and at azimuth 252 deg. The sun will be at an altitude of -28 deg. (At predicted centre line for longitude W 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.25 path widths.
The probabilities to see a positive event:

Centre line: ~  96 %
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.
