Station Map for the Occultation by (3118) Claytonsmith at Wednesday, 2009 January 21 (~ 21:37 UT)

V-Magnitude of target star TYC 2421-00701-1: 9.4 mag
Spectral type K7
The UCAC2 gives a „pseudo-R magnitude“ of  8.8 mag

The max duration is expected to be 2.8 sec with a max drop of 6.2 mag.
The event will take place at an altitude of  77 deg and at azimuth 206 deg. The sun will be at an altitude of – 60 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ±  2.54 path widths.
The probabilities to see a positive event:

Centre line: ~  16 %
Path limits: ~  15 %
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.
