Station Map for the Occultation by (378) Holmia at Thursday, 2009 October 29 (~ 00:05 UT)

V-magnitude of target star TYC 1351-00554-1: 11.1 mag
Johnson B-V Colour Index: + 0.2
UCAC instrumental “pseudo-R” fit-model magnitude: 10.8 mag (data from UCAC3)

The max duration is expected to be 2.8 sec with a max drop of 3.4 mag.
The event will take place at an altitude of  30 deg and at azimuth 99 deg. The sun will be at an altitude of -52 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ± 1.57 path widths.
The probabilities to see a positive event:

Centre line: ~  25 %
Path limits: ~  24 %
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.
Let other observers know about you observing plans: Announce you station with OccultWatcher !
