Station Map for the Occultation by (1829) Dawson at Monday, 2009 November 02 (~ 05:23 UT)

Trans-Atlantic Event!
Shadow crosses Canada and U.S.A. too.

V-magnitude of target star TYC 1929-01002-1: 8.8 mag
Spectral Type K0
Johnson B-V Colour Index: + 1.2
UCAC instrumental „pseudo-R“ fit-model magnitude: 8.5 mag (data from UCAC3)

The max duration is expected to be 1.1 sec with a max drop of 7.0 mag.
The event will take place at an altitude of  68 deg and at azimuth 205 deg. The sun will be at an altitude of -10 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 2.37 path widths.
The probabilities to see a positive event:

Centre line: ~ 17 %
Path limits: ~  16 %
1 sigma lines:  ~ 8 %
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!
