CNEOS predicts that the large NEO, (517681) 2015 DE198, will make a close approach on 2024-Apr-15 14:08±<00:01 at a distance of 0.04699 AU moving at V Relative=14.18 km/sec, H=18.9 magnitude, diameter 440 m - 990 m and 'Rarity'=1. As of 2024 Feb 26 it had a 25919 day observation arc, a Condition Code=0 and Earth MOID=0.0439028 AU. The orbit is well defined.
Using elements downloaded from the MPC on 2024 Feb 26, ST4v predicts that this NEO will reach maximum brightness of 15.8 magnitude on 2024 Apr 9 around 0100 EDT when the NEO will be 0.07 AU distant moving through Ursa Major at 11"/min. ST4v predicts that this MP is visible from dark skies from March 30 (16.6 magnitude in Canes Venatici, 3"/min) to Apr 12 (16.3 magnitude in Camelopardalis, 21"/min). The close approach occurs in daylight as seen from Columbus, Ohio.
