Station Map for the Occultation by (202) Chryseis at Monday, 2009 November 09 (~ 03:27 UT)
V-Magnitude of target star TYC 0059-00966-1: 12.0 mag
Johnson B-V Colour Index: + 0.3
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.5 mag (data from UCAC3)
In the case of an occultation, the combined light of the asteroid and the star will drop by 0.6 mag to 11.8 mag (the magnitude of the asteroid).
The max duration is expected to be 6.7 sec.
The event will take place at an altitude of 32 deg and at azimuth 244 deg. The sun will be at an altitude of -36 deg. (At predicted centre line for longitude 0 deg)
There is a 1 sigma uncertainty interval of ± 0.46 path widths.
The probabilities to see a positive event:
Centre line: ~ 72 %
Path limits: ~ 49 %
1 sigma lines: ~ 16 %
2 sigma lines: ~ 2 %
(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)
PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even with a small probability.
