Nakano Note (Nakano wa Kangaeru noda) NK 5036 C/2023 H5 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 60 observations 2022 Dec. 1 to 2023 June 15. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second. See an orbit in CBET 5272 (same orbit).
