Station Map for the Occultation by (40) Harmonia at Monday, 2011 November 21 (~ 02:00 UT)

V-Magnitude of target star TYC 0644-00335-1: 11.1 mag
Johnson B-V Colour Index: + 0.6
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.0 mag (data from UCAC3)

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

The max duration is expected to be 14.4 sec with a max drop of 0.24 mag.
The event will take place at an altitude of 37 deg and at azimuth 248 deg. The sun will be at an altitude of -50 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.17 path widths.
The probabilities to see a positive event:

Centre line: ~ 100 %
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.
Let other observers know about you observing plans: Announce your station with OccultWatcher !
