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,

| Close Approach of 2025 DU2 |

CNEOS predicts that the newly-discovered NEO,2025 DU2 will make a close approach on 2025 March 5. Currently the Condition Code for this object is 8, so the orbit isn't very well defined. It's predicted to be best viewed from the southern hemisphere, but may be visible in a 13" telescope on the morning of March 5 in Virgo from Columbus, Ohio.
I'll post an update when the orbit is better defined.

CNEOS predicts that the medium-sized, Apollo-class NEO, 2018 RC2, will make a close approach on 2025-Mar-08 11:45±<00:01 UT at a distance of 0.00506 AU moving with V Relative=12.49 km/sec, H=23.1 magnitude, diameter 64 m - 140 m and 'Rarity'=2. There is a 2365 day observation arc, the Condition Code=1 and the Earth MOID=0.00306707 AU. The solution date was 2025-Feb-27 05:16:24 PST. The initial reported observation was by Mt. Lemmon Survey on 2018-09-07. This object is too small to make the list of Potentially Hazardous Asteroids. It will make another close approach at approximately this distance on 2100 Mar 9.
Using MPC's elements for 2025 Feb 27 0000 UT, ST4.1.11.14 Visual Pro predicts that this NEO will reach a peak brightness of 13.6 magnitude on March 7 2200 EST when the NEO will be 855.9 k km distant, traveling through Cancer at 165"/minute. Close approach (to the nearest hour) is predicted on 2025 March 8 at 0700 EST with the NEO 759.4k km distant at 14 magnitude traveling through Monocerous at 197"/minute, but in daylight below the horizon in Columbus,Ohio. It's predicted to be brighter than 16th magnitude from March 5 in Ursa Major to March 8 in Caelum.
Here's the Object Info dialog for this object:
Since this NEO will pass very close, parallax will affect the apparent positions. To calculate the most accurate positions, download MPC's elements near the time of your observations or get elements from the HORZONS website.
Good hunting,
Phil S.
