Nakano Note (Nakano wa Kangaeru noda) NK 5360 C/2015 K7
The following improved orbital elements, by S. Nakano, are from 59 observations 2013 Mar. 9 to 2015 May 26. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.32 arc second. See an orbit in CBET 5482 (same orbit).
