Polymele Occultation 2021-12-22 (G* = 15.2)

The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2021 December 22 UT. The prediction is based on a Gaia DR2 position for the star, corrected for parallax and proper motion, and the v20210113232746 orbit estimate for Polymele, which has a 1-sigma cross-track uncertainty of 22.3 km.

Geocentric mid-time of the event is 18:23:16 UT. Star position is RA 03:41:19.6, Dec +23:49:52 (J2000), and its magnitude is 15.10. Polymele is moving at 12 km/s with respect to the star and its diameter is estimated to be 21 km, so central chords are expected to last 1.8 seconds.
