Eurybates Occultation 2020-09-16 (G* = 14.5)

The interactive map below shows our current prediction for the stellar occultation by (3548) Eurybates on 2020 September 16 UT. The prediction is based on a Gaia DR2 position for the star, corrected for parallax and proper motion, and the v20200831203410 orbit estimate for Eurybates, which has a 1-sigma cross-track uncertainty of 10.8 km.

Geocentric mid-time of the event is 11:03:02 UT. Star position is RA 01:28:57.8, Dec +04:28:34 (J2000), and its magnitude is 15.52. Eurybates is moving at 13 km/s with respect to the star and its diameter is estimated to be 66 km, so central chords are expected to last 5.2 seconds. Eurybates' magnitude is predicted to be 16.6 at event time, so it will be 2.7 times fainter than the star.
