Station Maps for the Occultation by (285) Regina at Monday, 2009 November 16 (~ 02:05 UT)


Magnitude of target star 2UCAC 44249318: 11.1 mag
UCAC instrumental “pseudo-R” fit-model magnitude: 11.3 mag (data from UCAC3)

The max duration is expected to be 4.5 sec with a max drop of 3.7 mag.
The event will take place at an altitude of 33 deg and at azimuth 288 deg. The sun will be at an altitude of -42 deg. (At predicted centre line for longitude E 10 deg)

There is a 1 sigma uncertainty interval of  ± 2.04 path widths.
The probabilities to see a positive event:

Centre line: ~  19 %
Path limits: ~  19 %
1 sigma lines:  ~ 9 %
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 !
