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.
