Station Maps for the Occultation by (4186) Tamashima at
Monday, 2008 October 27 (~ 22:09 UT)

NORTH and SOUTH

V-Magnitude of target star TYC 5331-01004-1: 9.8 mag
Johnson B-V Colour Index: + 0.6
The UCAC2 gives a „pseudo-R magnitude“ of 9.6 mag

The max duration is expected to be 3.1 sec with a max drop of 6.6 mag.
The event will take place at an altitude of 13 deg and at azimuth 119 deg. The sun will be at an altitude of -55 deg. (At predicted centre line for latitude N 47 deg)

There is a 1 sigma uncertainty interval of ± 5.99 path widths.
The probabilities to see a positive event:

Centre line: ~ 7 %
Path limits: ~ 7 %
1 sigma lines: ~ 4 %

(Calculation according to Raymond Dusser, E.A.O.N. Circular #10)

PLEASE REMEMBER: Predictions are sometimes wrong. Please observe even with a small probability.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
