Eurybates Occultation 2024-10-25 (G* = 12.3)

The interactive map below shows our current prediction for the occultation by (3548) Eurybates on 2024 October 25 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20230506003011 orbit estimate for Eurybates, which is derived from eurybates_20221019a_n6ogh1.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 10.0 km and a 1-sigma downtrack uncertainty of 0.1 sec for this event (these are placeholder values).

The geocentric mid-time of the event is 02:45:04.9 UT. The J2000 star position is RA 11:23:55.3 (11.3987033), Dec +10:52:22 (10.872685), and its magnitude is 12.28. Eurybates is moving at 33.9 km/s with respect to the star and its diameter is estimated to be 69.3 km, so central chords are expected to last 2.0 seconds.

Of-date coordinates for the target star on event night are RA 11:25:12.6 (11.4201667), Dec +10:44:10 (10.736111).
