Nakano Note (Nakano wa Kangaeru noda) NK 4304 C/2020 P3 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 227 observations 2020 Aug. 9 to Nov. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. The comet has passed 5.88 AU from Uranus on 2014 July 29 UT. See an orbit CBET 4830. Epoch = 2021 Apr. 16.0 TT T = 2021 Apr. 20.97259 +/- 0.07134 (m.e.)
