Station Map for the Occultation by (1758) Naantali at Friday, 2009 January 02 (~ 19:48 UT)

V-Magnitude of target star TYC 1337-01443-1: 10.3 mag
Johnson B-V Colour Index: + 0.9
The UCAC2 gives a „pseudo-R magnitude“ of 9.9 mag

The max duration is expected to be 2.1 sec with a max drop of 4.9 mag.
The event will take place at an altitude of 36 deg and at azimuth 95 deg. The sun will be at an altitude of -34 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ±  1.90 path widths.
The probabilities to see a positive event:

Centre line: ~ 21 %
Path limits: ~  20 %
1 sigma lines:  ~ 10 %
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.
