Station Map for the Occultation by (694) Ekard at Friday, 2009 November 20 (~ 19:29 UT)

Magnitude of target star 2UCAC 32295035: 11.7 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 12.5 mag (data from UCAC3)

DOUBLE STAR!
Name: BAL 1235
The WDS has two measurements:
Year 1896  PA 322  deg    SEP 7.3 arcsec
Year 1909  PA 320  deg    SEP 7.2 arcsec
The component A ( about 1 mag brighter than B) will be occulted.

The max duration is expected to be 4.1 sec with a max drop of 1.4 mag.
The event will take place at an altitude of 37 deg and at azimuth 237 deg. The sun will be at an altitude of -44 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ± 0.27 path widths.
The probabilities to see a positive event:

Centre line: ~  94 %
Path limits: ~  50 %
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 you station with OccultWatcher !
