Nakano Note (Nakano wa Kangaeru noda) NK 3351 C/2016 B1 (NEOWISE)
The following improved orbital elements, S. Nakano, are from 115 observations 2016 Jan. 17 to 2017 Mar. 3. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. Residuals for 2017 March observations were -6" for Right Ascension and -5" for Declination from an orbit in NK 3331 (= HICQ 2017). See the previous orbits in NK 3165 and NK 3331.
