Station Maps for the Occultation by (221) Eos at Saturday, 2010 August 28 (~ 22:26 UT)


Magnitude of target star 2UCAC 29944567: 12.6 mag
UCAC instrumental “pseudo-R” fit-model magnitude: 12.6 mag (data from UCAC3)

The max duration is expected to be 12.9 sec with a max drop of 0.46 mag.
The event will take place at an altitude of 26 deg and at azimuth 136 deg. The sun will be at an altitude of -31 deg. (At predicted centre line for latitude N 50 deg)

There is a 1 sigma uncertainty interval of  ± 1.13 path widths.
The probabilities to see a positive event:

Centre line: ~  34 %
Path limits: ~  31 %
1 sigma lines:  ~ 13 %
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 !

Good luck with your observation!
