Nakano Note (Nakano wa Kangaeru noda) NK 4661 A/2021 X2

The following improved orbital elements, by S. Nakano, are from 43 observations 2021 Oct. 30 to 2022 Feb. 5. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.22 arc second. The comet will pass 2.57 AU from Jupiter on 2022 Oct. 28 UT. Epoch = 2022 June 30.0 TT T = 2022 July 8.16557 +/- 0.00609 (m.e.)
