The max duration is expected to be 8.9 sec with a max drop of 2.2 mag.
The event will take place at an altitude of  34 deg and at azimuth 156 deg. The sun will be at an altitude of – 51 deg. (At predicted centre line for longitude 0 deg)

There is a 1 sigma uncertainty interval of  ± 0.31  path widths.
The probabilities to see a positive event:

Centre line: ~  90 %
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.
