Station Map for the Occultation by (4342) Freud at Friday, 2011 November 25 (~ 22:33 UT)
V-Magnitude of target star TYC 1312-01598-1: 8.7 mag
Spectral type: F0
Johnson B-V Colour Index: + 0.3
UCAC instrumental „pseudo-R“ fit-model magnitude: 8.4 mag (data from UCAC3)
The max duration is expected to be 1.8 sec with a max drop of 7.8 mag.
The event will take place at an altitude of 47 deg and at azimuth 123 deg. The sun will be at an altitude of -63 deg. (At predicted centre line for longitude E 10 deg)
There is a 1 sigma uncertainty interval of ± 4.69 path widths.
The probabilities to see a positive event:
Centre line: ~ 9 %
Path limits: ~ 8 %
1 sigma lines: ~ 5 %
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.
