Nakano Note (Nakano wa Kangaeru noda) NK 2477 C/2012 F3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 69 observations 2012 Jan. 19 to 2013 Mar. 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. See the previous orbits in HICQ 2012, NK 2403 and NK 2467. Epoch = 2015 Apr. 8.0 TT T = 2015 Apr. 6.57059 +/- 0.07997 (m.e.)
