Nakano Note (Nakano wa Kangaeru noda) NK 3052 C/2015 D3 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 73 observations 2015 Feb. 17 to 2016 Jan. 17. 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. Recent observations show the residuals of +2" for Right Ascension and +3" for Declination from an orbit in HICQ 2015. Epoch = 2016 May 12.0 TT T = 2016 Apr. 30.88974 +/- 0.07774 (m.e.)
