Station Map for the Occultation by (4711) Kathy at Thursday, 2009 January 15 (~ 18:30 UT)
V-Magnitude of target star TYC 0042-01409-1: 9.1 mag
Johnson B-V Colour Index: + 1.1
Spectral type K0
The UCAC2 gives a „pseudo-R magnitude“ of 8.9 mag
The max duration is expected to be 0.7 sec with a max drop of 6.9 mag.
The event will take place at an altitude of 41 deg and at azimuth 177 deg. The sun will be at an altitude of – 20 deg. (At predicted centre line for longitude 0 deg)
There is a 1 sigma uncertainty interval of ± 3.86 path widths.
The probabilities to see a positive event:
Centre line: ~ 10 %
Path limits: ~ 10 %
1 sigma lines: ~ 6 %
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.
