The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2020 October 9 UT. The prediction is based on a Gaia DR2 position for the star, corrected for parallax and proper motion, and the v20200923192610 orbit estimate for Polymele, which has a 1-sigma cross-track uncertainty of 5.5 km.
Geocentric mid-time of the event is 23:55:13 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.
