Nakano Note (Nakano wa Kangaeru noda) NK 4589 C/2021 P1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 96 observations 2021 July 14 to Nov. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.26 arc second. The comet has passed 2.76 AU from Jupiter on 2021 Oct. 11 UT. See an orbit in CBET 5020. Epoch = 2022 May 21.0 TT T = 2022 June 2.09830 +/- 0.01023 (m.e.)
