CNEOS predicts that the newly discovered NEO, 2024 HY, will make a close approach on 2024-Apr-22 17:50±<00:01 UT at a distance of 0.01471 AU moving with V Realative=9.22 km/sec, H=23.3 magnitude, diameter 57 m - 130 m and 'Rarity'=1. There is a 1 day observation arc, the Condition Code=7 and the Earth MOID=0.00745199 AU. The solution date is 2024-Apr-22 05:48:07 PDT. The initial reported observation was by ATLAS Chile, Rio Hurtado on 2024-04-20. CNEOS predicts that it will pass within 0.00832 AU on 2036 Apr 23, so it will probably make it on MPC's list of Potentially Hazardous Asteroids (PHAs).
Using MPC's elements downloaded on 2024 Apr 22 0000 UT, ST4Visual predicts that this NEO reached a maximum brightness of 15.6 magnitude on April 21 ~2300 EDT while travelling through Crater at 50"/minute. This object should be visible in a 13" telescope on April 22 at 2200 EDT moving through Leo at 15.9 magnitude and 0.01 AU distant with apparent motion of 52.1"/minute. Close approach is predicted (to the nearest hour) on 2024 Apr 22 1400 EDT when the NEO is predicted to be 15.8 magnitude moving through Leo at 52.1"/minute, but in daylight and below the horizon as seen from Columbus, Ohio.
