The interactive map below shows our current prediction for the stellar occulation by (11351) Leucus on 2018 December 11 UT. The prediction is based on a Gaia DR2 position for the star and the v20181205164552 orbit estimate for Leucus. This orbit includes all astrometry up through October 2017.
Geocentric mid-time of the event is 10:33:42 UT. Star position is RA 20:56:55.0, Dec -06:44:00 (J2000), and its magnitude is 14.30. Leucus is moving at 30 km/s with respect to the star and its diameter is estimated to be 45 km, so central chords are expected to last 1.5 seconds.
