Nakano Note (Nakano wa Kangaeru noda) NK 4023 A/2019 T2
The following improved orbital elements, by S. Nakano, are from 53 observations 2019 Aug. 26 to Dec. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.27 arc second. The object will pass 2.87 AU from Jupiter on 2020 Nov. 29 UT. Epoch = 2021 Apr. 16.0 TT T = 2021 Apr. 22.33449 +/- 0.03388 (m.e.)
