Nakano Note (Nakano wa Kangaeru noda) NK 2958 P/2014 C1 (TOTAS)
The following improved orbital elements, by S. Nakano, are from 47 observations 2014 Feb. 1 to May 8. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.54 arc second. See an orbit in HICQ 2014. Epoch = 2013 Dec. 14.0 TT T = 2013 Dec. 18.95356 +/- 0.05473 (m.e.)
