The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2023 January 11 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220331172718 orbit estimate for Polymele, which is derived from polymele_20220204a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 5 km and a 1-sigma downtrack uncertainty of 1 sec for this event (these are placeholder values).
Geocentric mid-time of the event is 22:18:47 UT. The J2000 star position is RA 06:52:07.5 (6.8687427), Dec +35:55:14 (35.920459), and its magnitude is 10.97. Polymele is moving at 16 km/s with respect to the star and its diameter is estimated to be 26 km, so central chords are expected to last 1.6 seconds.
Of-date coordinates for the target star on event night are RA 06:53:40.0 (6.8944444), Dec +35:53:28 (35.891111).
