The interactive map below shows our current prediction for the stellar occultation by (617) Patroclus on 2021 March 26 UT. The prediction is based on a Gaia DR2 position for the star and the v20181130000734 orbit estimate for Patroclus.
Patroclus is part of a binary, but we have not plotted both components yet. The ground-track will be updated before the event.
Geocentric mid-time of the event is 09:26:01 UT. Star position is RA 16:16:49.9, Dec -27:23:51 (J2000), and its magnitude is 14.77. Patroclus is moving at 7 km/s with respect to the star and its diameter is estimated to be 127 km, so central chords are expected to last 18 seconds.
