Station Map for the Occultation by (641) Agnes at Tuesday, 2010 October 19 (~ 00:44 UT)

V-Magnitude of target star TYC 1879-00949-1: 10.3 mag
Johnson B-V Colour Index: + 1.0
UCAC instrumental “pseudo-R” fit-model magnitude: 9.6 mag (data from UCAC3)

The max duration is expected to be 1.1 sec with a max drop of 5.5 mag.
The event will take place at an altitude of 37 deg and at azimuth 100 deg. The sun will be at an altitude of -44 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 2.27 path widths.
The probabilities to see a positive event:

Centre line: ~  17 %
Path limits: ~  17 %
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 !
