The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2022 August 26 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220623223035 orbit estimate for Polymele, which is derived from polymele_sbp_20220623a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 1.2 km and a 1-sigma downtrack uncertainty of 0.2 sec for this event.
Geocentric mid-time of the event is 04:04:12 UT. The J2000 star position is RA 06:42:56.2 (6.715611), Dec +30:31:42 (30.52833), and its magnitude is 12.80. Polymele is moving at 31 km/s with respect to the star. The shadow width is estimated to be 15 km in the crosstrack direction and 26 km in the downtrack direction, so central chords are expected to last 0.8 seconds.
Of-date coordinates for the target star on event night are RA 06:44:23.4 (6.739833), Dec +30:30:15 (30.50417).
