CNEOS predicts that the kilometer-sized, Apollo-class NEA, (164216) 2004 OT11, will make a close approach on 2026-Jul-26 22:01±<00:01 UT at a distance of 0.08217 AU moving with V Relative=16.88 km/sec, H=17.2 magnitude, diameter 950 m - 2.1 km and 'Rarity'=2. As of 2026 July 14 there is a 8022 day observation arc, the Condition Code=0 and the Earth MOID=0.0204111 AU. The solution date was 2026-Jul-15 07:45:29 PDT. Discovered 2004-07-27 by LINEAR at Socorro. This object is on the MPC's list of Potentially Hazardous Asteroids (PHAs) that you can download using SkyTools. The close approach on 2105-Jul-16 17:49±<00:01 UT at 0.02707 AU is very close to the Earth MOID.
Using MPC's orbital elements for the epoch 2026 July 17 0000 UT, ST4.1.11.21 Visual Pro predicts that (164216) 2004 OT11 will reach a peak brightness of 14.8 magnitude on the evening of July 29 to August 2. It's well placed on July 30 in Serpens Caput at 0.091 AU distance traveling at 13.4"/minute. Close approach is predicted (to the nearest hour) on 2026 July 26 at 1800 EDT (2200 UT) with the NEA traveling through Bootes at 0.082 AU at 15.0 magnitude and 16.7"/minute, but in daylight in Columbus, Ohio. This object is predicted to be brighter than 16 magnitude from July 21 (in Virgo) to August 15 (in Lyra).
Here's the Object Info dialog for (164216) OT11:
The orbit for this NEA is well defined and it should be easy to find once it becomes bright enough for your scope.
Good hunting,
