Station Map for the Occultation by (515) Athalia at Tuesday, 2010 January 05 (~ 22:00 UT)

V-Magnitude of target star TYC 1386-01139-1: 11.3 mag
Johnson B-V Colour Index: + 0.7
UCAC instrumental “pseudo-R” fit-model magnitude: 10.7 mag (data from UCAC3)

The max duration is expected to be 3.6 sec with a max drop of 3.9 mag.
The event will take place at an altitude of  44 deg and at azimuth 123 deg. The sun will be at an altitude of -55 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ± 1.11 path widths.
The probabilities to see a positive event:

Centre line: ~  35 %
Path limits: ~  31 %
1 sigma lines:  ~ 13 %
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.
