Station Map for the Occultation by (708) Raphaela at Friday, 2011 April 01 (~ 21:04 UT)

V-Magnitude of target star TYC 1871-00946-1: 10.1 mag
Johnson B-V Colour Index: + 0.2
UCAC instrumental „pseudo-R“ fit-model magnitude: 10.1 mag (data from UCAC3)

The max duration is expected to be 1.0 sec with a max drop of 5.8 mag.
The event will take place at an altitude of 32 deg and at azimuth 271 deg. The sun will be at an altitude of -26 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ± 1.21 path widths.
The probabilities to see a positive event:

Centre line: ~  21 %
Path limits: ~  20 %
1 sigma lines:  ~ 10 %
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 !
