Station Map for the Occultation by (245) Vera at Wednesday, 2009 September 09 (~ 04:55 UT)

Magnitude of target star 2UCAC 40323088: 11.4 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.51 mag (data from UCAC3)

The max duration is expected to be 3.1 sec with a max drop of  1.9 mag.
The event will take place at an altitude of 55 deg and at azimuth 108 deg. The sun will be at an altitude of -12 deg. (At predicted centre line for longitude W 06 deg)

There is a 1 sigma uncertainty interval of  ± 1.45 path widths.
The probabilities to see a positive event:

Centre line: ~  27 %
Path limits: ~  26 %
1 sigma lines:  ~ 11 %
2 sigma lines: ~ 1 %

(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 !
