Polymele Occultation 2022-08-26 (G* = 13.6)

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 and its diameter is estimated to be 29 km, so central chords are expected to last 0.9 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).
