Nakano Note (Nakano wa Kangaeru noda) NK 4344 C/2019 S4 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 228 observations 2019 Sept. 17 to 2020 Oct. 30. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.52 arc second. See the previous orbits in CBET 4738, HICQ 2020, NK 4059, NK 4091 and NK 4146. Epoch = 2020 Apr. 21.0 TT T = 2020 Apr. 7.93883 +/- 0.00081 (m.e.)
