Station Map for the Occultation by (977) Philippa at Wednesday, 2009 February 11 (~ 04:10 UT)

V-Magnitude of target star TYC 2479-00747-1: 12.4 mag
Johnson B-V Colour Index: 0
The UCAC2 gives a „pseudo-R magnitude“ of  11.6 mag

The max duration is expected to be 6.8 sec with a max drop of  2.2 mag.
The event will take place at an altitude of 25 deg and at azimuth 298 deg. The sun will be at an altitude of -32 deg. (At predicted centre line for longitude E 01 deg)

There is a 1 sigma uncertainty interval of  ± 0.61 path widths.
The probabilities to see a positive event:

Centre line: ~  59 %
Path limits: ~  45 %
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.
