Nakano Note (Nakano wa Kangaeru noda) NK 2967 P/2014 MG4 (Spacewatch-PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 100 observations 2014 June 20 to Nov. 23. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.61 arc second. See the previous orbit in NK 2800. Epoch = 2013 May 28.0 TT T = 2013 June 13.62091 +/- 0.03238 (m.e.)
