Station Map for the Occultation by (28) Bellona at Thursday, 2011 March 17 (~ 21:50 UT)

V-magnitude of target star TYC 1354-00368-1: 11.2 mag
Johnson B-V Colour Index: + 0.3
UCAC instrumental „pseudo-R“ fit-model magnitude: 11.6 mag (data from UCAC3)

The max duration is expected to be 14.8 sec with a max drop of 0.8 mag.
The event will take place at an altitude of 43 deg and at azimuth 242 deg. The sun will be at an altitude of -35 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ± 0.21 path widths.
The probabilities to see a positive event:

Centre line: ~  98 %
Path limits: ~  50 %
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 !
