Polymele Occultation 2026-07-14 (G* = 15.0)

The interactive map below shows our current prediction for the occultation by (15094) Polymele on 2026 July 14 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20230505204437 orbit estimate for Polymele, which is derived from polymele_20230214a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 4.5 km and a 1-sigma downtrack uncertainty of 1.8 sec for this event.

The geocentric mid-time of the event is 00:25:52.1 UT. The J2000 star position is RA 13:14:23.0 (13.2397186), Dec -02:33:55 (-2.565176), and its magnitude is 14.60. Polymele is moving at 14.2 km/s with respect to the star and its diameter is estimated to be 20.0 km, so central chords are expected to last 1.4 seconds.

Of-date coordinates for the target star on event night are RA 13:15:45.1 (13.2625278), Dec -02:42:18 (-2.705000).
