Good luck & clear skies!

Phil, the rocks have similar orbits is several ways except for inclination and size. UL21 has a radius of ~1.4Km while MK sports a tiny 0.101Km. Their inclinations are vastly different. UL21 having an i=34.88° while the tiny rock is 8.46°. UL21 is an Apollo class so its orbit crosses inside that of ours. MK is an Amor class, so does not. Most Amors cross the orbit of Mars.
Most of their other orbital elements are similar, although the Longitude of perihelion stands out a bit - UL21 = 200° vs MK = 291°
Again, it will be very interesting if I can nab UL21 moving ~3.5'/min into the west edge of Hydra out of Corvus.
Then next head to the Tail of the Scorpion to tag a much faster moving but brighter tiny rock - 2024 MK.
Unfortunately, I'm unable to get a proper ephemeris for 2024 MK at this time.
I've added this track but recommend doing your own from your location using date of observation osculating elements.
