Nakano Note (Nakano wa Kangaeru noda) NK 5359 C/2024 U1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 93 observations 2023 Nov. 13 to 2024 Dec. 10. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.37 arc second. The comet has passed 1.44 AU from Jupiter on 2024 Sept. 25 UT. See an orbit in CBET 5471 (= NK 5324). Epoch = 2024 June 19.0 TT T = 2024 June 30.56721 +/- 0.00334 (m.e.)
