Station Map for the Occultation by (199) Byblis at Sunday, 2010 October 17 (~ 19:33 UT)

V-Magnitude of target star TYC 5846-00196-1: 11.8 mag
Johnson B-V Colour Index: + 0.5
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.6 mag (data from UCAC3)

The max duration is expected to be 5.7 sec with a max drop of 1.7 mag.
The event will take place at an altitude of 15 deg and at azimuth 134 deg. The sun will be at an altitude of -27 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 1.79 path widths.
The probabilities to see a positive event:

Centre line: ~  22 %
Path limits: ~  21 %
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 you station with OccultWatcher !
