Nakano Note (Nakano wa Kangaeru noda) NK 3352 C/2016 C1 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 109 observations 2016 Feb. 12 to 2017 Mar. 4. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.53 arc second. Residuals for 2017 March observations were +2" for Right Ascension and +3" for Declination from an orbit in NK 3180 (= HICQ 2017). The comet will pass 3.97 AU from Jupiter on 2016 Sept. 30 UT.
