Nakano Note (Nakano wa Kangaeru noda) NK 4567 C/2021 N3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 64 observations 2021 June 13 to Oct. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.19 arc second. The comet has passed 1.62 AU from Jupiter on 2021 June 23 and will pass 3.78 AU from Saturn on 2022 Apr. 16 UT. See an orbit in CBET 5003.
