Nakano Note (Nakano wa Kangaeru noda) NK 2904 C/2014 M2 (Christensen)
The following improved orbital elements, by S. Nakano, are from 51 observations 2014 June 25 to Sept. 29. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.57 arc second. Epoch = 2014 July 2.0 TT T = 2014 July 9.76363 +/- 2.98816 (m.e.)
