Nakano Note (Nakano wa Kangaeru noda) NK 5577 C/2024 D1 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 65 observations 2023 Dec. 27 to 2026 Jan. 22. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. See the previous orbits in NK 5376 and CBET 5542 (= NK 5404). Epoch = 2027 Dec. 21.0 TT T = 2027 Dec. 3.78969 +/- 0.00745 (m.e.)
