Nakano Note (Nakano wa Kangaeru noda) NK 2842 P/2013 P4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 202 observations 2013 Aug. 15 to 2015 Feb. 20. 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 the previous orbits in NK 2601 and NK 2783. Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 12.42462 +/- 0.02058 (m.e.)
