Nakano Note (Nakano wa Kangaeru noda) NK 4730 192P/Shoemaker-Levy 1
The following improved orbital elements, by S. Nakano, are from 133 observations 1990 to 2008. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.75 arc second. The comet has passed 0.62 AU from Jupiter on 2006 June 19 UT. See the previous orbits in NK 552, NK 1060, YC 2571 (= NK 1539). Epoch = 2007 Dec. 6.0 TT T = 2007 Dec. 17.33683 +/- 0.00016 (m.e.)
