Polymele Occultation 2022-03-27 (G* = 11.1)

The interactive map below shows our current prediction for the stellar occultation by (15094) Polymele on 2022 March 27 UT. The prediction is based on a Gaia eDR3 position for the star, corrected for parallax and proper motion, and the v20220207222755 orbit estimate for Polymele, which is derived from polymele_20220204a.bsp. This ephemeris has a 1-sigma crosstrack uncertainty of 1.6 km and a 1-sigma downtrack uncertainty of <0.1 sec for this event.

Geocentric mid-time of the event is 01:53:40 UT. The J2000 star position is RA 04:03:50.8 (4.064111), Dec +25:44:55 (25.74861), and its magnitude is 10.36. Polymele is moving at 29 km/s with respect to the star and its diameter is estimated to be 29 km, so central chords are expected to last 1.0 seconds.

Of-date coordinates for the target star on event night are RA 04:05:11.7 (4.086583), Dec +25:48:30 (25.80833).
