The interactive map below shows our current prediction for the stellar occulation by (15094) Polymele on 2020 October 9 UT. The prediction is based on a Gaia DR2 position for the star and the v20190110192757 orbit estimate for Polymele.
Geocentric mid-time of the event is 23:55:11 UT. Star position is RA 01:36:28.4, Dec +01:27:47 (J2000), and its magnitude is 15.05. Polymele is moving at 16 km/s with respect to the star and its diameter is estimated to be 21 km, so central chords are expected to last 1.3 seconds.
