Station Map for the Occultation by (1157) Arabia at Wednesday, 2009 September 09 (~ 21:17 UT)
V-Magnitude of target star HIP 116660: 8.7 mag
Spectral Type: F8
Johnson B-V Colour Index: + 0.5
The UCAC2 gives a „pseudo-R magnitude“ of 8.8 mag
The max duration is expected to be 2.7 sec with a max drop of 5.4 mag.
The event will take place at an altitude of 34 deg and at azimuth 120 deg. The sun will be at an altitude of -32 deg. (At predicted centre line for longitude 0 deg)
There is a 1 sigma uncertainty interval of ± 1.33 path widths.
The probabilities to see a positive event:
Centre line: ~ 29 %
Path limits: ~ 27 %
1 sigma lines: ~ 12 %
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.
