Station Map for the Occultation by (657) Gunlod at Friday, 2009 January 02 (~ 23:29 UT)

V-Magnitude of target star TYC 2403-00016-1: 11.4 mag
Johnson B-V Colour Index: + 0.5
The UCAC2 gives a „pseudo-R magnitude“ of 11.3 mag

The max duration is expected to be 3.5 sec with a max drop of 3.3 mag.
The event will take place at an altitude of 62 deg and at azimuth 224 deg. The sun will be at an altitude of -59 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ±  0.85 path widths.
The probabilities to see a positive event:

Centre line: ~  44 %
Path limits: ~  38 %
1 sigma lines:  ~ 14 %
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 !
