The interactive map below shows our current prediction for the stellar occultation by (11351) Leucus on 2019 October 2 UT. The prediction is based on a Gaia DR2 position for the star and the v20191001193256 orbit estimate for Leucus. This orbit includes all astrometry through September 2019, and is validated against past successful Leucus occultations.
Geocentric mid-time of the event is 07:19:31 UT. Star position is RA 22:41:10.1, Dec +06:45:39 (J2000), and its magnitude is 13.52. Leucus is moving at 14 km/s with respect to the star and its diameter is estimated to be 30 km, so central chords are expected to last 2.1 seconds.
