Station Map for the Occultation by (370) Modestia at Sunday, 2009 April 19 (~ 20:03 UT)

V-Magnitude of target star TYC 5508-01191-1: 10.3 mag
Johnson B-V Colour Index: + 0.6
The UCAC2 gives a „pseudo-R magnitude“ of  10.3 mag

The max duration is expected to be 3.3 sec with a max drop of 4.3 mag.
The event will take place at an altitude of 27 deg and at azimuth 179 deg. The sun will be at an altitude of -17 deg. (At predicted centre line for longitude E 20 deg)

There is a 1 sigma uncertainty interval of  ± 1.41 path widths.
The probabilities to see a positive event:

Centre line: ~  28 %
Path limits: ~  26 %
1 sigma lines:  ~ 12 %
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 !
