Nakano Note (Nakano wa Kangaeru noda) NK 3254 341P/Gibbs
The following improved orbital elements, by S. Nakano, are from 182 observations 2007 to 2016. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.77 arc second. 2016 October observations show the residuals of -12" for Right Ascension and -3" for Declination from a linked orbit in NK 3217. See the previous orbits in NK 2492 (= HICQ 2016) and NK 3217. Epoch = 2016 May 12.0 TT T = 2016 May 26.83658 +/- 0.00693 (m.e.)
