The interactive map below shows our current prediction for the stellar occulation by (15094) Polymele on 2021 October 23 UT. The prediction is based on a Gaia DR2 position for the star and the v20181128232513 orbit estimate for Polymele.
Geocentric mid-time of the event is 10:13:34 UT. Star position is RA 04:15:38.8, Dec +23:44:24 (J2000), and its magnitude is 16.66. Polymele is moving at 11 km/s with respect to the star and its diameter is estimated to be 21 km, so central chords are expected to last 1.9 seconds.
