Nakano Note (Nakano wa Kangaeru noda) NK 3531 356P/WISE
The following improved orbital elements, by S. Nakano, are from 162 observations 2009 to 2018. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.62 arc second. Residuals on 2018 January observations were +11" mainly for Right Ascension from a linked orbit in NK 3390 (= HICQ 2018). See the previous orbits in NK 2738 and NK 3390. Epoch = 2018 Jan. 2.0 TT T = 2017 Dec. 17.10894 +/- 0.00248 (m.e.)
