Station Map for the Occultation by (2114) Wallenquist at Monday, 2009 February 16 (~ 01:48 UT)

V-Magnitude of target star TYC 1894-00123-1: 9.8 mag
Johnson B-V Colour Index: + 0.3
Spectral Type F8
The UCAC2 gives a „pseudo-R magnitude“ of  9.8 mag

The max duration is expected to be 4.5 sec with a max drop of  6.6 mag.
The event will take place at an altitude of 22 deg and at azimuth 280 deg. The sun will be at an altitude of -37 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ± 2.56 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 !
