Station Map for the Occultation by (506) Marion at Tuesday, 2008 December 30 (~ 01:04 UT)

V-Magnitude of target star TYC 0835-00953-1: 11.5 mag
Johnson B-V Colour Index: + 0.3
The UCAC2 gives a “pseudo-R magnitude” of  11.3 mag

The max duration is expected to be 17.3 sec with a max drop of 1.9 mag.
The event will take place at an altitude of 58 deg and at azimuth 164 deg. The sun will be at an altitude of -50 deg. (At predicted centre line for longitude E 25 deg)

There is a 1 sigma uncertainty interval of  ±  0.48 path widths.
The probabilities to see a positive event:

Centre line: ~ 70 %
Path limits: ~  48 %
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 !
