Station Map for the Occultation by (116) Sirona at Sunday, 2011 December 04 (~ 02:53 UT)
V-Magnitude of target star TYC 0282-00753-1: 7.7 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 6.8 mag (data from UCAC3)
The max duration is expected to be 3.3 sec with a max drop of 5.1 mag.
The event will take place at an altitude of 19 deg and at azimuth 113 deg. The sun will be at an altitude of -38 deg. (At predicted centre line for longitude E 10 deg)
There is a 1 sigma uncertainty interval of ± 0.70 path widths.
The probabilities to see a positive event:
Centre line: ~ 52 %
Path limits: ~ 42 %
1 sigma lines: ~ 15 %
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.
