The interactive map below shows our current prediction for the stellar occulation by (3548) Eurybates on 2019 September 29 UT. The prediction is based on a Gaia DR2 position for the star and the v20190110191002 orbit estimate for Eurybates.
Geocentric mid-time of the event is 00:45:16 UT. Star position is RA 23:00:24.5, Dec -15:27:20 (J2000), and its magnitude is 14.04. Eurybates is moving at 14 km/s with respect to the star and its diameter is estimated to be 72 km, so central chords are expected to last 5.1 seconds.
