Station Map for the Occultation by (1970) Sumeria at Tuesday, 2009 March 17 (~ 19:32 UT)

V-Magnitude of target star TYC 1869-00408-1: 9.1 mag
Johnson B-V Colour Index: + 0.6
Spectral Type A7
The UCAC2 gives a “pseudo-R magnitude” of 9.0 mag

The max duration is expected to be 1.2 sec with a max drop of  7.7 mag.
The event will take place at an altitude of 60 deg and at azimuth 245 deg. The sun will be at an altitude of -20 deg. (At predicted centre line for longitude E 06 deg)

There is a 1 sigma uncertainty interval of  ± 2.36 path widths.
The probabilities to see a positive event:

Centre line: ~  17 %
Path limits: ~  16 %
1 sigma lines:  ~ 8 %
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 !
