Nakano Note (Nakano wa Kangaeru noda) NK 5195 P/PANSTARRS (2016 J1-B = 2020 Y6-B)
The following improved orbital elements, by S. Nakano, are from 76 observations 2004 to 2022, including planetary perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas, Vesta, and non-gravitational effect of style II. The mean residual is +/- 0.54 arc second. 2010 April observations were included in this computation as Nucleus B. See in NK 4815, following comments on there. Residuals for the recovery observations were +140" for Right Ascension and +18" for Declination from the prediction in NK 3988 with the delta-T correction = -0.09 day. See the previous orbits in NK 3234, NK 3988 and NK 4815 and also NK 5194 (CBET 5367; same orbit) for nucleus A (principal component).
