CNEOS predicts that the medium-sized NEO, 2025 BC10, will make a close approach on 2025-Apr-05 10:12±<00:01 UT at a distance of 0.02477 AU moving with V Relative=22.92 km/sec, H=19.4 magnitude, diameter 360 m - 800 m and 'Rarity'=2. There is currently a 61 day observation arc, the Condition Code=5 and the Earth MOID=0.00482072 AU. The solution date was 2025-Mar-30 06:53:58 PDT. Initial observation was on 2025 Jan 28 by Pan-STARRS 1, Haleakala. This object is on MPC's list of Potentially Hazardous Asteroids (PHAs) due to its size and Earth MOID, but this is the closest approach predicted for over 100 years.
Using MPC's orbital elements for 2025 Mar 30 0000 UT, ST4.1.11.14 Visual Pro predicts that this NEO will make its close approach (to the nearest hour) on 2025 Apr 5 0600 EDT (1000 UT) when the NEO will be estimated 14.5 magnitude traveling through Gemini at 75"/minute in morning twilight, but below the horizon in Columbus, Ohio. Peak brightness of 13.8 magnitude is predicted on April 3 2300 EDT with the NEO 0.03 AU distant traveling through Leo at 53"/minute. The evening of April 2 and morning of April 3 will be nearly as favorable. It's already 14.7 magnitude in Virgo.
Here's the Object Info dialog for 2025 BC10:
This bright NEO should put on quite a show for those able to observe it.
Good hunting,
