Nakano Note (Nakano wa Kangaeru noda) NK 4710 P/2022 D1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 95 observations 2022 Jan. 19 to May 10. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. See an orbit in CBET 5104. Epoch = 2021 Aug. 14.0 TT T = 2021 Aug. 28.20222 +/- 0.02396 (m.e.)
