Nakano Note (Nakano wa Kangaeru noda) NK 4436 P/2020 V3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 101 observations 2020 Oct. 17 to 2021 Feb. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.43 arc second. See the previous orbits in CBET 4888 and NK 4392 (= HICQ 2021). Epoch = 2021 Jan. 26.0 TT T = 2021 Feb. 7.13992 +/- 0.87387 (m.e.)
