Nakano Note (Nakano wa Kangaeru noda) NK 3448 C/2015 T2 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 156 observations 2015 Oct. 9 to 2017 Sept. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. Residuals for recent observations were -2" mainly for Right Ascension from an orbit in NK 3316 (= HICQ 2017). See the previous orbits in NK 3076, NK 3249 and NK 3316.
