CNEOS predicts that the newly discovered Apollo class NEA, 2025 XV, will make a close approach on 2025-Dec-18 03:48±00:02 UT at a distance of 0.01735 AU moving with V relative=9.55 km/sec, H=22.8 magnitude, diameter 75 m - 170 m and 'Rarity'=1. There is currently a 5 day observation arc, the Condition Code=7 and the Earth MOID=0.0164718 AU. The solution date was 2025-Dec-12 05:24:22 PST. The initial reported observation was by ATLAS-TDO on 2025-12-08. The observation arc was extended by observations on 2025-12-6, 7 & 8 by Palomar Mountain--ZTF. The close approach time has changed by -1 minute from December 10 to December 12, but the uncertainty on December 10 was ±00:09.
The orbit is still being refined so observers should check the CNEOS website for the status of this NEA. It's currently predicted to be 16.7 magnitude in Perseus, but it should exceed 16 magnitude on December 14 and reach a peak brightness of 15.1 in Taurus on the night of December 16.
Good hunting.
