Notes. Osculating heliocentric orbital elements at epoch MJD 60,200.0 from the MPC catalog: semimajor axis a, eccentricity e, inclination I, longitude of node Ω, and argument of perihelion ω. singleopposition orbits are listed at the end of the table. The third column gives the absolute magnitude H. The last column indicates, whether the asteroid has been detected by CSS during the phase 2 operations (Y=yes). We note a very small, singleopposition asteroids 2019 NF93, 2021 JQ73, 2023 JD27 and 2023 NV2 very likely members of the Hobson family too. However, their orbits, especially for 2019 NF93 based on observations spanning less than a week, are still very uncertain.
