Station Map for the Occultation by (1902) Shaposhnikov at Friday, 2011 April 22 (~ 03:15 UT)

Trans-Atlantic-Event!
Path will cross Canada too.

Magnitude of target star 2UCAC 32545066: 11.8 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 12.1 mag (data from UCAC3)

The max duration is expected to be 5.9 sec with a max drop of 3.9 mag.
The event will take place at an altitude of 29 deg and at azimuth 246 deg. The sun will be at an altitude of -24 deg. (At predicted centre line for longitude W 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.93 path widths.
The probabilities to see a positive event:

Centre line: ~  41 %
Path limits: ~  36 %
1 sigma lines:  ~ 14 %
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 !
