Nakano Note (Nakano wa Kangaeru noda) NK 2772 C/2001 O2 (NEAT)
The following improved orbital elements, by S. Nakano, are from 68 observations 2001 July 25 to 2002 Aug. 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.66 arc second. See a parabolic orbit in NK 1513.
