Polymele Occultation 2024-02-26 (G* = 12.7)

The interactive map below shows our current prediction for the occultation by (15094) Polymele on 2024 February 26 UT. The prediction is based on a Gaia DR3 position for the star, corrected for parallax and proper motion, and the v20230427175312 orbit estimate for Polymele, which is derived from polymele_20230214a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 2.9 km and a 1-sigma downtrack uncertainty of 0.5 sec for this event.

The geocentric mid-time of the event is 13:06:17.5 UT. The J2000 star position is RA 09:40:33.9 (9.6760715), Dec +30:44:35 (30.743114), and its magnitude is 12.20. Polymele is moving at 15.3 km/s with respect to the star and its diameter is estimated to be 20.0 km, so central chords are expected to last 1.3 seconds.

Of-date coordinates for the target star on event night are RA 09:41:59.0 (9.6997222), Dec +30:37:57 (30.632500).
