Nakano Note (Nakano wa Kangaeru noda) NK 2428 C/2011 M1 (LINEAR)
The following improved orbital elements, by S. Nakano, are from 98 observations 2011 June 22 to Aug. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.81 arc second. The comet has passed 2.95 AU from Jupiter on 2010 May 31 UT. See an orbit in HICQ 2012. Epoch = 2011 Aug. 27.0 TT T = 2011 Sept. 7.56622 +/- 0.01299 (m.e.)
