Nakano Note (Nakano wa Kangaeru noda) NK 3234 P/2016 J1 - B (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 26 observations 2016 Apr. 14 to June 12. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.43 arc second. If Nucleus B was separated from the principal component A at the perihelion of the last passage in 2010, the separated velocity was -0.16 m/s. Epoch = 2016 June 21.0 TT T = 2016 June 24.12888 +/- 0.03151 (m.e.)
