Station Map for the Occultation by (1135) Colchis at Monday, 2008 December 29 (~ 20:57 UT)

V-Magnitude of target star 2UCAC 42390990: 12.6 mag

The max duration is expected to be 4.1 sec with a max drop of 1.5 mag.
The event will take place at an altitude of 57 deg and at azimuth 114 deg. The sun will be at an altitude of -51 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ±  1.73 path widths.
The probabilities to see a positive event:

Centre line: ~ 23 %
Path limits: ~  22 %
1 sigma lines:  ~10 %
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 !
