Nakano Note (Nakano wa Kangaeru noda) NK 5217 C/2022 H1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 68 observations 2022 Mar. 2 to 2024 Apr. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.47 arc second. 2024 April observations show the residuals of +94" for Right Ascension and -38" for Declination from an orbit in NK 4883 (= CH 2023). See the previous orbits in CBET 5120 and NK 4883. Epoch = 2024 Jan. 11.0 TT T = 2024 Jan. 19.25264 +/- 0.11509 (m.e.)
