The interactive map below shows our current prediction for the occultation by (3548) Eurybates on 2023 November 23 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20231114190358 orbit estimate for Eurybates, which is derived from eurybates_20231113a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 3.6 km and a 1-sigma downtrack uncertainty of 0.6 sec for this event.
The geocentric mid-time of the event is 09:28:09.2 UT. The J2000 star position is RA 09:45:39.2 (9.7608809), Dec +22:28:45 (22.479173), and its magnitude is 15.41. Eurybates is moving at 9.0 km/s with respect to the star and its diameter is estimated to be 66.0 km, so central chords are expected to last 7.3 seconds.
Of-date coordinates for the target star on event night are RA 09:46:59.9 (9.7833056), Dec +22:22:05 (22.368056).
