Nakano Note (Nakano wa Kangaeru noda) NK 4841 C/2022 F1 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 110 observations 2022 Mar. 30 to 2022 Oct. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.55 arc second. The comet will pass 1.71 AU from Saturn on 2025 Aug. 1 UT. See the previous orbits in CBET 5112, NK 4777 and NK 4812. Epoch = 2022 Aug. 9.0 TT T = 2022 Aug. 5.19899 +/- 0.13091 (m.e.)
