Nakano Note (Nakano wa Kangaeru noda) NK 5160 P/2023 V6 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 53 observations 2023 Oct. 16 to Dec. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.34 arc second. The comet will pass 0.36 AU from Jupiter on 2031 July 30 UT. See an orbit in CBET 5317. Epoch = 2023 Jan. 16.0 TT T = 2022 Dec. 30.90790 +/- 0.27306 (m.e.)
