Polymele Occultation 2023-02-04 (G* = 13.1)

The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2023 February 4 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220626022932 orbit estimate for Polymele, which is derived from polymele_sbp_20220623a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 1.3 km and a 1-sigma downtrack uncertainty of 0.6 sec for this event.

Geocentric mid-time of the event is 01:39:43 UT. The J2000 star position is RA 06:38:54.7 (6.6485156), Dec +36:01:27 (36.024221), and its magnitude is 13.29. Polymele is moving at 11 km/s with respect to the star and its diameter is estimated to be 26 km, so central chords are expected to last 2.4 seconds.

Of-date coordinates for the target star on event night are RA 06:40:27.8 (6.6743889), Dec +36:00:07 (36.001944).
