Station Maps for the Occultation by (541) Deborah at Friday, 2009 December 18 (~ 19:46 UT)


V-Magnitude of target star TYC 1813-01183-1: 11.3 mag
Johnson B-V Colour Index: +0.6
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.2 mag (data from UCAC3)

The max duration is expected to be 5.1 sec with a max drop of 3.3 mag.
The event will take place at an altitude of  56 deg and at azimuth 133 deg. The sun will be at an altitude of -42 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ± 0.62 path widths.
The probabilities to see a positive event:

Centre line: ~  58 %
Path limits: ~  45 %
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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !

Good luck with your observation!
