The interactive map below shows our current prediction for the stellar occultation by (3548) Eurybates on 2021 November 20 UT. The prediction is based on a Gaia DR2 position for the star, corrected for parallax and proper motion, and the v20210113210921 orbit estimate for Eurybates, which has a 1-sigma cross-track uncertainty of 14.6 km.
Geocentric mid-time of the event is 04:47:30 UT. Star position is RA 03:40:08.6, Dec +22:09:53 (J2000), and its magnitude is 13.28. Eurybates is moving at 16 km/s with respect to the star and its diameter is estimated to be 66 km, so central chords are expected to last 4.1 seconds.
