Leucus Occultation 2022-03-15 (G* = 15.3)

The interactive map below shows our current prediction for the stellar occultation by (11351) Leucus on 2022 March 15 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220312204023 orbit estimate for Leucus, which is derived from leucus_20220214a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 2.1 km and a 1-sigma downtrack uncertainty of 0.4 sec for this event.

Geocentric mid-time of the event is 03:17:00 UT. The J2000 star position is RA 03:49:23.9 (3.823305), Dec +20:15:12 (20.25331), and its magnitude is 15.61. Leucus is moving at 25.5 km/s with respect to the star and its diameter is estimated to be 41 km, so central chords are expected to last 1.6 seconds.

Of-date coordinates for the target star on event night are RA 03:50:41.4 (3.844833), Dec +20:19:11 (20.31972).
