Station Map for the Occultation by (1036) Ganymed at Thursday, 2011 June 16 (~ 22:19 UT)

V-Magnitude of target star TYC 2695-02598-1: 12.3 mag
Johnson B-V Colour Index: + 1.2
UCAC instrumental „pseudo-R“ fit-model magnitude: 12.6 mag (data from UCAC3)

Please notice:
In the case of an occultation, the combined light of the asteroid and the star will drop by 0.4 mag to 11.3 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 1.7 sec with a max drop of 0.36 mag.
The event will take place at an altitude of 38 deg and at azimuth 78 deg. The sun will be at an altitude of -18 deg. (At predicted centre line for longitude E 05 deg 02 min)

There is a 1 sigma uncertainty interval of  ± 0.65 path widths.
The probabilities to see a positive event:

Centre line: ~ 54 %
Path limits: ~  43 %
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.
Let other observers know about you observing plans: Announce your station with OccultWatcher !

Good luck with your observation!
