Station Maps for the Occultation by (1625) The NORC at Wednesday, 2009 January 21 (~ 03:14 UT)
NORTH and SOUTH
V-Magnitude of target star TYC 6733-00727-1: 11.4 mag
Johnson B-V Colour Index: + 1.0
The UCAC2 gives a „pseudo-R magnitude“ of 10.9 mag
The max duration is expected to be 1.9 sec with a max drop of 4.2 mag.
The event will take place at an altitude of 14 deg and at azimuth 153 deg. The sun will be at an altitude of – 37 deg. (At predicted centre line for latitude N 45 deg)
There is a 1 sigma uncertainty interval of ± 1.48 path widths.
The probabilities to see a positive event:
Centre line: ~ 26 %
Path limits: ~ 25 %
1 sigma lines: ~ 11 %
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.
