Station Maps for the Occultation by (639) Latona at Thursday, 2009 January 15 (~ 21:08 UT)
EAST and WEST
V-Magnitude of target star TYC 1864-00746-1: 10.4 mag
Johnson B-V Colour Index: + 0.3
The UCAC2 gives a “pseudo-R magnitude” of 10.3 mag
The max duration is expected to be 6.3 sec with a max drop of 2.6 mag.
The event will take place at an altitude of 64 deg and at azimuth 162 deg. The sun will be at an altitude of – 51 deg. (At predicted centre line for longitude E 10 deg)
There is a 1 sigma uncertainty interval of ± 0.50 path widths.
The probabilities to see a positive event:
Centre line: ~ 68 %
Path limits: ~ 48 %
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.
