Nakano Note (Nakano wa Kangaeru noda) NK 3024 327P/Van Ness
The following improved orbital elements, by S. Nakano, are from 94 observations 2002 to 2015. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.69 arc second. The recent 2015 October-November observations show the residuals of -15" and +16" off from a linked orbit in NK 2994. See the previous orbits in NK 983 and NK 2994.
