Station Map for the Occultation by (2617) Jiangxi at Wednesday, 2010 January 06 (~ 19:38 UT)

Magnitude of target star 2UCAC 43608980: 12.7 mag
UCAC instrumental „pseudo-R“ fit-model magnitude: 12.9 mag (data from UCAC3)

The max duration is expected to be 4.7 sec with a max drop of 1.5 mag.
The event will take place at an altitude of  44 deg and at azimuth 83 deg. The sun will be at an altitude of -39 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ± 1.62 path widths.
The probabilities to see a positive event:

Centre line: ~  24 %
Path limits: ~  23 %
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 !
