The interactive map below shows our current prediction for the occultation by (11351) Leucus on 2023 November 28 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20230508154200 orbit estimate for Leucus, which is derived from leucus_20220214a.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 06:44:14.8 UT. The J2000 star position is RA 08:58:22.4 (8.9728966), Dec +06:33:35 (6.559712), and its magnitude is 13.47. Leucus is moving at 6.5 km/s with respect to the star and its diameter is estimated to be 41.0 km, so central chords are expected to last 6.4 seconds.
Of-date coordinates for the target star on event night are RA 08:59:38.5 (8.9940278), Dec +06:27:58 (6.466111).
