Station Map for the Occultation by (979) Ilsewa at Monday, 2009 February 02 (~ 18:57 UT)

V-Magnitude of target star TYC 0766-01692-1: 12.2 mag
Johnson B-V Colour Index: + 0.3
The UCAC2 gives a „pseudo-R magnitude“ of  12.6 mag

The max duration is expected to be 3.0 sec with a max drop of  2.9 mag.
The event will take place at an altitude of 35 deg and at azimuth 111 deg. The sun will be at an altitude of -19 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 1.35 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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
