CNEOS predicts that the newly discovered Aten class NEO, 2025 RL2, will make a close approach on 2025-Sep-19 08:57±00:38 UT at a distance of 0.00145 AU moving with V Relative=9.68 km/sec, H=26.0 magnitude, diameter 17 m - 37 m and 'Rarity'=2. As of September 15, there is a 2 day observation arc, the Condition Code=7 and the Earth MOID=0.000219316 AU. The solution date was 2025-Sep-15 06:52:13 PDT. The initial reported observation was by Kitt Peak-Bok on 2025-09-13.
SkyTools 4.1.11.18 Visual Pro predicts that 2025 RL2 will reach a peak brightness of 13.7 magnitude near midnight on September 19 with 2025 RL2 traveling through Pegasus at ~340"/minute. It's still predicted to be 14.1 magnitude at close approach in Aquila, but below the horizon in Columbus, Ohio. Observers farther west should be able to catch it closer to the time of close approach.
I'll post an update after the orbit has been refined further.
There were several bright MPs that passed us on September 11-13 that were detected after they'd already passed by like 2025 RO2 and 2025 RQ2.
