Station Map for the Occultation by (272) Antonia at Wednesday, 2011 October 05 (~ 04:37 UT)

V-Magnitude of target star TYC 0645-00211-1: 11.3 mag
Johnson B-V Colour Index: + 0.8
UCAC instrumental “pseudo-R” fit-model magnitude: 11.1 mag (data from UCAC3)

Trans-Atlantic Event!
Path will cross SE Canada and U.S.A. too.

The max duration is expected to be 3.1 sec with a max drop of 3.6 mag.
The event will take place at an altitude of 37 deg and at azimuth 245 deg. The sun will be at an altitude of -11 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 1.73 path widths.
The probabilities to see a positive event:

Centre line: ~ 23 %
Path limits: ~ 22 %
1 sigma lines:  ~ 10 %
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 your station with OccultWatcher !
