Station Map for the Occultation by (312) Pierretta at Saturday, 2008 December 20 (~ 19:35 UT)

V-Magnitude of target star TYC 2397-00753-1: 12.0 mag
Johnson B-V Colour Index: + 0.2
The UCAC2 gives a “pseudo-R magnitude” of  11.9 mag

The max duration is expected to be 3.4 sec with a max drop of 1.8 mag.
The event will take place at an altitude of 59 deg and at azimuth 94 deg. The sun will be at an altitude of -44 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ±  0.73 path widths.
The probabilities to see a positive event:

Centre line: ~ 51 %
Path limits: ~  41 %
1 sigma lines:  ~15 %
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 !
