The interactive map below shows our current prediction for the stellar occultation by (3548) Eurybates on 2022 October 23 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220208025705 orbit estimate for Eurybates, which is derived from eurybates_20220204a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 4.7 km and a 1-sigma downtrack uncertainty of 0.9 sec for this event.
Geocentric mid-time of the event is 02:07:27 UT. The J2000 star position is RA 06:59:12.9 (6.986917), Dec +29:16:24 (29.27333), and its magnitude is 8.69. Eurybates is moving at 6.5 km/s with respect to the star and its diameter is estimated to be 66 km, so central chords are expected to last 10 seconds.
Of-date coordinates for the target star on event night are RA 07:00:39.6 (7.011000), Dec +29:14:26 (29.24056).
