Nakano Note (Nakano wa Kangaeru noda) NK 5378 C/2024 J2 (Wierzchos)
The following improved orbital elements, by S. Nakano, are from 245 observations 2024 Mar. 12 to 2025 Feb. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.74 arc second. 2024 February observations show the residuals of -3" for Right Ascension and +4" for Declination from an orbit in NK 5348. See the previous orbits in CBET 5394, NK 5273, NK 5307 and NK 5348. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 19.78242 +/- 0.00049 (m.e.)
