Nakano Note (Nakano wa Kangaeru noda) NK 3272 347P/PANSTARRS
The following improved orbital elements, by S. Nakano, are from 132 observations 2002 to 2016. 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. 2002 observations were found on Palomar/NEAT frames. See the previous orbit in NK 3236. Epoch = 2016 Sept. 9.0 TT T = 2016 Sept.11.39616 +/- 0.00362 (m.e.)
