Polymele Occultation 2022-12-27 (G* = 14.5)

The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2022 December 27 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220626020753 orbit estimate for Polymele, which is derived from polymele_sbp_20220623a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 2.7 km and a 1-sigma downtrack uncertainty of 0.4 sec for this event.

Geocentric mid-time of the event is 05:20:14 UT. The J2000 star position is RA 07:02:45.2 (7.045889), Dec +35:27:39 (35.46083), and its magnitude is 14.40. Polymele is moving at 16 km/s with respect to the star and its diameter is estimated to be 29 km, so central chords are expected to last 1.7 seconds.

Of-date coordinates for the target star on event night are RA 07:04:16.9 (7.071361), Dec +35:25:33 (35.42583).
