Nakano Note (Nakano wa Kangaeru noda) NK 3592 P/2017 W3 (Gibbs)
The following improved orbital elements, by S. Nakano, are from 122 observations 2017 Nov. 27 to 2018 May 10. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.64 arc second. See the previus orbit in NK 3576. Epoch = 2018 Feb. 11.0 TT T = 2018 Feb. 24.99527 +/- 0.04240 (m.e.)
