Nakano Note (Nakano wa Kangaeru noda) NK 4770 C/2014 A5 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 42 observations 2014 Jan. 4 to 2016 May 7. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. The comet has passed 0.78 AU from Jupiter on 2014 May 26 UT. See the previous orbit in NK 2826. Epoch = 2014 Aug. 11.0 TT T = 2014 Aug. 13.62385 +/- 0.00131 (m.e.)
