Nakano Note (Nakano wa Kangaeru noda) NK 2403 C/2012 F3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 35 observations 2012 Jan. 19 to Dec. 18. 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. The comet will pass 4.29 AU from Uranus on 2022 Aug. 7 UT. See an orbit in HICQ 2012. Epoch = 2015 Apr. 8.0 TT T = 2015 Apr. 6.82027 +/- 0.20030 (m.e.)
