Station Map for the Occultation by (58) Concordia at Tuesday, 2009 November 24 (~ 01:56 UT)

Trans-Atlantic Event!
Path is crossing SE U.S.A. too. Star at low altitude.

V-Magnitude of target star TYC 1313-01182-1: 9.8 mag
Johnson B-V Colour Index: + 0.7
UCAC instrumental „pseudo-R“ fit-model magnitude: 9.3 mag (data from UCAC3)

DOUBLE STAR!
Name: HEI 114
Magnitude 9.5 and 11.5
WDS shows two measurements:
Year 1982    SEP 1.3 arcsec   PA 328 deg
Year 1997    SEP 1.3 arcsec   PA 337 deg

The max duration is expected to be 10.7 sec with a max drop of 3.4 mag.
The event will take place at an altitude of 53 deg and at azimuth 189 deg. The sun will be at an altitude of -47 deg. (At predicted centre line for longitude E 05 deg)

There is a 1 sigma uncertainty interval of  ± 0.59 path widths.
The probabilities to see a positive event:

Centre line: ~  60 %
Path limits: ~  45 %
1 sigma lines:  ~ 16 %
2 sigma lines: ~ 2 %

(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 !
