Nakano Note (Nakano wa Kangaeru noda) NK 3348 P/2014 W4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 78 observations 2014 Oct. 25 to 2017 Feb. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.33 arc second. See the previous orbits in NK 3027, NK 3136 and NK 3162 (= HICQ 2017). Epoch = 2016 Jan. 13.0 TT T = 2015 Dec. 29.68398 +/- 0.00086 (m.e.)
