The interactive map below shows our current prediction for the stellar occultation by (617) Patroclus on 2021 May 9 UT. The prediction is based on a Gaia DR2 position for the star and the v20210113194659 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 08:38:02 UT. Star position is RA 16:00:08.3, Dec -28:49:20 (J2000), and its magnitude is 11.49. Patroclus is moving at 17.5 km/s with respect to the star and its diameter is estimated to be 127 km, so central chords are expected to last 7.3 seconds.
