Station Map for the Occultation by (1036) Ganymed at Sunday, 2011 September 25 (~ 02:46 UT)
V-Magnitude of target star TYC 3670-00426-1: 11.4 mag
Johnson B-V Colour Index: + 1.1
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.0 mag (data from UCAC3)
In the case of an occultation, the combined light of the asteroid and the star will drop by 0.2 mag to 9.3 mag (the magnitude of the asteroid).
OCCULTATION BY A NEA (Near Earth Asteroid)!
There are more occultations to come in the next months crossing Europe!
Have a look for future events at the special webpage:
The max duration is expected to be 3.0 sec with a max drop of 0.15 mag.
The event will take place at an altitude of 72 deg and at azimuth 289 deg. The sun will be at an altitude of -24 deg. (At predicted centre line for latitude N 52 deg 6min)
There is a 1 sigma uncertainty interval of ± 0.44 path widths.
The probabilities to see a positive event:
Centre line: ~ 74 %
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.

Good luck with your observation!
