The interactive map below shows our current prediction for the stellar occultation by (617) Patroclus on 2019 March 18 UT. The prediction is based on a Gaia DR2 position for the star and the v20181128184527 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 01:39:25 UT. Star position is RA 13:10:51.5, Dec +09:05:18 (J2000), and its magnitude is 11.22. Patroclus is moving at 18 km/s with respect to the star and its diameter is estimated to be 127 km, so central chords are expected to last 7.1 seconds.
