Patroclus Occultation 2021-03-26 (G* = 12.4)

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. Patroclus' magnitude is predicted to be 15.7 at event time, so it will be 2.3 times fainter than the star.
