Nakano Note (Nakano wa Kangaeru noda) NK 4053 C/2018 R3 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 253 observations 2018 Aug. 8 to 2020 Mar. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.70 arc second. Residuals on 2020 February/March observations were +10" mainly for Declination from an orbit in NK 3954 (= HICQ 2020). Non-gravitational effects seems to be in comet motion. See the previous orbits in NK 3822, NK 3855 and NK 3954. Epoch = 2019 June 6.0 TT T = 2019 June 7.19750 +/- 0.00009 (m.e.)
