The max duration is expected to be 5.0 sec with a max drop of 2.3 mag.
The event will take place at an altitude of  31 deg and at azimuth 91 deg. The sun will be at an altitude of -38 deg. (At predicted centre line for longitude E 15 deg)

There is a 1 sigma uncertainty interval of  ± 0.77 path widths.
The probabilities to see a positive event:

Centre line: ~  48 %
Path limits: ~  40 %
1 sigma lines:  ~ 15 %
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 !
