Predictions of stellar occultations by the main planetary satellites

Observations of a stellar occultations help to better determine the size and the shape of the occulting body, as well as its astrometric position at the milli-arcsecond level precision. Only the main moons of giant planets Jupiter, Saturn, Uranus and Neptune are considered in the event prediction database.

Predictions are provided over period 2023-2032, up to visual magnitude 12 for the biggest satellites, and magnitude 14 for other satellites. For each stellar occultation event prediction, the database provides circumstances and observational data, date and timing of the occultation, star position and magnitude, excepted duration, etc.
