CNEOS predicts that the large, Apollo-class, NEA, (221455) 2006 BC10, will make a close approach on 2026-Aug-28 15:47±<00:01 UT at a distance of 0.02396 AU moving with V Relative=19.00 km/sec, H=19.5 magnitude, diameter 330 m - 740 m and 'Rarity'=2. As of 2026 Jan 22, there is a 7303 day observation arc, the Condition Code=0 and the Earth MOID=0.00575443 AU. The solution date was 2026-Jan-22 05:49:02 PST. Discovered 2006-01-23 by Spacewatch at Kitt Peak This NEA is on the MPC's list of Potentially Hazardous Asteroids (PHAs) that you can downlosd using SkyTools.
The next close approach to earth on 2052-Mar-19 04:02 ± 00:02 (TDB) will be close to the Earth MOID at 0.00783 AU. Unfortunately the osculating orbital elements available now don't give accurate positions that far in the future.
Using MPC's orbital elements for the epoch 2026 Aug 4 0000 UT, ST4.1.11.21 Visual Pro predicts that (221455) 2006 BC10 will reach a peak brightness of 13.8 magnitude on 2026 Aug 29 at 2300 EDT traveling through Telescopium at 0.029 AU distant and 44"/minute, but on the horizon as seen from Columbus, Ohio (40°N). Close approach is predicted (to the nearest hour) on 2026 Aug 28 at 1200 EDT (1600 UT) with the NEA 0.024 AU distant traveling through Norma at 14.4 magnitude and 66"/minute, but in daylight and below the horizon in Columbus. This object will be best observed from the southern hemisphere. It should be visible in a 13" telescope from 40°N from August 30 (in Microscopium) to September 8 (in Aquarius).
Here's the Object Info dialog for (221455) 2006 BC10:
The orbit for this object is well defined, so the orbital elements available from MPC should yield accurate positions.
Good hunting,
