Station Map for the Occultation by (405) Thia at Friday, 2009 December 18 (~ 03:02 UT)

Trans-Atlantic Event!
Shadow will cross Florida, U.S.A. and Mexico too.

Magnitude of target star 2UCAC 38221986: 12.4 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 12.8 mag (data from UCAC3)

The max duration is expected to be 9.2 sec with a max drop of 0.6 mag.
The event will take place at an altitude of 48 deg and at azimuth 245 deg. The sun will be at an altitude of -47 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.28 path widths.
The probabilities to see a positive event:

Centre line: ~  93 %
Path limits: ~  50 %
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 !
