Nakano Note (Nakano wa Kangaeru noda) NK 5307 C/2024 J2 (Wierzchos)
The following improved orbital elements, by S. Nakano, are from 114 observations 2024 Mar. 18 to Sept. 20. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.54 arc second. See the previous orbits in CBET 5394 and NK 5273. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 19.77148 +/- 0.00684 (m.e.)
