Nakano Note (Nakano wa Kangaeru noda) NK 3416 P/2013 W1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 103 observations 2013 Nov. 9 to 2014 Mar. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.67 arc second. See the previous orbit in NK 2643. Epoch = 2014 Mar. 4.0 TT T = 2014 Mar. 8.16931 +/- 0.00016 (m.e.)
