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,
