Nakano Note (Nakano wa Kangaeru noda) NK 3154 P/2015 V4 (PANSTARRS)
The following improved orbital elements, by T. Kobayashi, are from 60 observations 2015 Nov. 3 to 2016 Apr. 13. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.31 arc second. See the previous orbit in NK 3078. Epoch = 2016 Sept. 9.0 TT T = 2016 Aug. 28.13238 +/- 0.05293 (m.e.)
