Nakano Note (Nakano wa Kangaeru noda) NK 3542 P/2017 S2 (PANSTARRS)

The following improved orbital elements, by S. Nakano, are from 62 observations 2017 Aug. 22 to 2018 Jan. 16. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.35 arc second. See the previous orbits in HICQ 2018 and NK 3524. Epoch = 2017 Sept. 4.0 TT T = 2017 Aug. 29.33627 +/- 0.00993 (m.e.)
