The interactive map below shows our current prediction for the occultation by (15094) Polymele on 2025 April 22 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20230427152134 orbit estimate for Polymele, which is derived from polymele_20230214a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 9.6 km and a 1-sigma downtrack uncertainty of 1.2 sec for this event.
The geocentric mid-time of the event is 09:34:47.5 UT. The J2000 star position is RA 11:37:07.8 (11.6188208), Dec +15:58:09 (15.969080), and its magnitude is 11.22. Polymele is moving at 10.8 km/s with respect to the star and its diameter is estimated to be 20.0 km, so central chords are expected to last 1.8 seconds.
Of-date coordinates for the target star on event night are RA 11:38:26.5 (11.6406944), Dec +15:49:44 (15.828889).
