Station Map for the Occultation by (694) Ekard at Thursday, 2009 July 09 (~ 22:42 UT)

Magnitude of target star 2UCAC 35660565: 11.6 mag

In the case of an occultation, the combined light of the asteroid and the star will drop by 0.8 mag to 11.6 mag (the magnitude of the asteroid) .

The max duration is expected to be 14.3 sec with a max drop of  0.8 mag.
The event will take place at an altitude of 42 deg and at azimuth 127 deg. The sun will be at an altitude of -19 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.47 path widths.
The probabilities to see a positive event:

Centre line: ~  71 %
Path limits: ~  48 %
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.
