CNEOS predicts that the newly discovered NEO, 2025 KF, will make a close approach on 2025-May-21 17:26±00:04 UT at a distance of 0.00077 AU moving with V Relative=11.58 km/sec, H=27.1 magnitude, diameter 10 m - 23 m and 'Rarity'=1. There is a 1 day observation arc, the Condition Code=7 and the Earth MOID=0.000805912 AU. The solution date was 2025-May-20 06:23:01 PDT. The initial reported observation was by MAP, San Pedro de Atacama on 2025-05-19.
Using MPC's orbital elements for the epoch 2025 May 20 0000 UT, ST4.1.1.14 Visual Pro predicts that this NEO will reach a peak brightness of 13.8 magnitude on 2025 May 21 at 1200 EDT at a distance of only 133.3k km traveling through Centaurus at 14.8"/second, but in daylight and below the horizon in Columbus, Ohio. Close approach is predicted (to the nearest hour) on 2025 May 21 1400 EDT (1800 UT) with the NEO at 14.5 magnitude and 119.5k km traveling through Hydrus at 19.2"/second in daylight and below the horizon in Columbus, Ohio. This object will be best from the southern hemisphere.
Here's the Object Info dialog for 2025 KF:
Since this object will pass very close and will be moving extremely fast, observers should follow the directions in the post at the top of this forum section to obtain orbital elements close to the time of their observations.
Good hunting,
