Patroclus Occultation 2021-05-04

The interactive map below shows our current prediction for the stellar occulation by (617) Patroclus on 2021 May 4 UT. The prediction is based on a Gaia DR2 position for the star and the v20181130000833 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 06:34:36 UT. Star position is RA 16:03:05.7, Dec -28:43:42 (J2000), and its magnitude is 13.76. Patroclus is moving at 17 km/s with respect to the star and its diameter is estimated to be 127 km, so central chords are expected to last 7.5 seconds.
