Station Map for the Occultation by (86) Semele at Thursday, 2008 December 18 (~ 04:01 UT)
V-Magnitude of target star TYC 1848-02237-1: 11.3 mag
Johnson B-V Colour Index: + 1.2
The UCAC2 gives a „pseudo-R magnitude“ of 11.0 mag
The max duration is expected to be 11.2 sec with a max drop of 1.1 mag.
The event will take place at an altitude of 34 deg and at azimuth 271 deg. The sun will be at an altitude of -37 deg. (At predicted centre line for longitude W 01 deg)
There is a 1 sigma uncertainty interval of ± 0.28 path widths.
The probabilities to see a positive event:
Centre line: ~ 93 %
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.
