The interactive map below shows our current prediction for the stellar occulation by (11351) Leucus on 2019 October 2 UT. The prediction is based on a Gaia DR2 position for the star and the v20181128175557 orbit estimate for Leucus. This orbit includes all astrometry up through October 2017.
Geocentric mid-time of the event is 07:19:30 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 45 km, so central chords are expected to last 3.2 seconds.
