Very important occultation!
Asteroid (319) Leona will occult alpha Orionis on 2023 December 12. The determination of the size and shape of the asteroid is highly desired. An accurate astrometric position obtained with measurements during this occultation can improve the prediction for the important occultation on December 12.
Predicted path with an update with data from JPL on Aug 23.
