Station Map for the Occultation by (1889) Pakhmutova at Monday, 2010 November 01 (~ 00:14 UT)

V-Magnitude of target star TYC 1845-00266-1: 10.7 mag
Johnson B-V Colour Index: + 0.5
UCAC instrumental „pseudo-R“ fit-model magnitude: 10.5 mag (data from UCAC3)
The max duration is expected to be 4.6 sec with a max drop of 4.9 mag.The event will take place at an altitude of 57 deg and at azimuth 124 deg. The sun will be at an altitude of -52 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 2.52 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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
