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.
