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 v20240216200109 orbit estimate for Polymele, which is derived from polymele_20240208a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 2.5 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 along-track diameter is estimated to be 26 km, so central chords are expected to last 1.7 seconds.
At the time of the occultation, the target star will be 43.9 degrees from the (96% illuminated) Moon. The predicted magnitude of Polymele is 18.63, so it will be 380 times fainter than the star it is occulting.
Of-date coordinates for the target star on event night are RA 09:41:59.0 (9.6997222), Dec +30:37:57 (30.632500).
