Station Map for the Occultation by (4103) Chahine at Saturday, 2009 October 10 (~ 00:46 UT)
V-magnitude of target star TYC 1790-00021-1: 8.6 mag
Spectral Type G0
Johnson B-V Colour Index: + 0.6
UCAC instrumental “pseudo-R” fit-model magnitude: 8.4 mag (data from UCAC3)
The max duration is expected to be 1.4 sec with a max drop of 5.2 mag.
The event will take place at an altitude of 64 deg and at azimuth 192 deg. The sun will be at an altitude of -36 deg. (At predicted centre line for longitude E 20 deg)
There is a 1 sigma uncertainty interval of ± 4.4 path widths.
The probabilities to see a positive event:
Centre line: ~ 9 %
Path limits: ~ 9 %
1 sigma lines: ~ 5 %
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.
