I just downloaded the MPC's list of Potentially Hazardous Asteroids (PHAs) and noticed that the kilometer-sized, Apollo-class NEA, (4183) Cuno is at opposition on 2026 Jul 10. It's currently in Capricornus at 14.5 magnitude. Peak brightness of 14.4 magnitude is predicted in early July 2026. The light curve is very broad due to Cuno's distance of 0.5 AU. The diameter=3.651 km and H=14.18. Discovered 1959-06-05 by Hoffmeister, C. at Bloemfontei.
The moon will interfere around July 1 and will actually occult Cuno from locations in Central America. Columbus, Ohio is too far north for an occultation to occur. Cuno passes ~14.25' north of the moon at ~0100 EDT (0500 UT) on 2026 Jul 1. Observers in the southwestern USA will see it pass even closer.
Good hunting,
