Station Map for the Occultation by (2252) CERGA at Tuesday, 2009 January 06 (~ 22:41  UT)

V-Magnitude of target star TYC 1892-00151-1: 9.7 mag
Johnson B-V Colour Index: + 0.7
The UCAC2 gives a „pseudo-R magnitude“ of 9.6 mag

The max duration is expected to be 1.2 sec with a max drop of 5.6 mag.
The event will take place at an altitude of 76 deg and at azimuth 150 deg. The sun will be at an altitude of -66 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ±  5.35 path widths.
The probabilities to see a positive event:

Centre line: ~  7 %
Path limits: ~  7 %
1 sigma lines:  ~ 4 %
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 !
