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.
