Eurybates Occultation 2022-09-06 (G* = 14.0)

The interactive map below shows our current prediction for the stellar occultation by (3548) Eurybates on 2022 September 6 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220815165116 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 18:40:54 UT. The J2000 star position is RA 06:36:03.5 (6.600977), Dec +28:22:19 (28.37198), and its magnitude is 14.23. Eurybates is moving at 25.8 km/s with respect to the star and its diameter is estimated to be 66 km, so central chords are expected to last 2.6 seconds.

Of-date coordinates for the target star on event night are RA 06:37:29.4 (6.624833), Dec +28:21:06 (28.35167).
