Station Maps for the Occultation by (37) Fides at Wednesday, 2010 September 01 (~ 01:43 UT)

WEST and EAST

Magnitude of target star 2UCAC 39795518: 11.2 mag
UCAC instrumental “pseudo-R” fit-model magnitude: 11.4 mag (data from UCAC3)

The max duration is expected to be 6.3 sec with a max drop of 0.9 mag.
The event will take place at an altitude of  43 deg and at azimuth 104 deg. The sun will be at an altitude of -28 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.45 path widths.
The probabilities to see a positive event:

Centre line: ~  74 %
Path limits: ~  49 %
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 !
