Nakano Note (Nakano wa Kangaeru noda) NK 4958 P/2022 P2 (ZTF)
The following improved orbital elements, by S. Nakano, are from 140 observations 2022 Aug. 9 to 2023 Mar. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.62 arc second. See the previous orbits in CBET 5165, NK 4890 and NK 4920. Epoch = 2022 June 30.0 TT T = 2022 July 10.76917 +/- 0.00066 (m.e.)
