Station Map for the Occultation by (1964) Walraven at Sunday, 2008 December 21 (~ 04:55 UT)

V-Magnitude of target star TYC 2401-00144-1: 10.4 mag
Johnson B-V Colour Index: + 0.5
The UCAC2 gives a „pseudo-R magnitude“ of  10.2 mag

The max duration is expected to be 1.5 sec with a max drop of 4.1 mag.
The event will take place at an altitude of 18 deg and at azimuth 306 deg. The sun will be at an altitude of -15 deg. (At predicted centre line for longitude E 20 deg)

There is a 1 sigma uncertainty interval of  ±  1.93 path widths.
The probabilities to see a positive event:

Centre line: ~ 20 %
Path limits: ~  20 %
1 sigma lines:  ~9 %
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 !

Good luck with your observation,
