Nakano Note (Nakano wa Kangaeru noda) NK 2429 C/2012 E3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 73 observations 2012 Mar. 14 to June 18. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.52 arc second. The comet has passed 3.57 AU from Jupiter on 2010 Feb. 2 UT. See an orbit in HICQ 2012. Epoch = 2011 Apr. 29.0 TT T = 2011 May 12.89399 +/- 0.03245 (m.e.)
