Nakano Note (Nakano wa Kangaeru noda) NK 4625 A/2021 E4
The following improved orbital elements, by S. Nakano, are from 79 observations 2020 Dec. 21 to 2022 Jan. 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.33 arc second. 2022 observations show the residuals of +5" mainly for Right Ascension from an orbit in NK 4492. Epoch = 2022 Apr. 11.0 TT T = 2022 Apr. 25.32404 +/- 0.00282 (m.e.)
