Nakano Note (Nakano wa Kangaeru noda) NK 5331 192P/Shoemaker-Levy 1
The following improved orbital elements, by S. Nakano, are from 208 observations 1990 to 2024, including planetary perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas, Vesta, and non-gravitational effect of style II. The mean residual is +/- 0.76 arc second. 2024 November observations show the residual of -13" mainly for Right Ascension from the recent linked orbit in NK 5252 with the delta-T correction = +0.015 day. 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), NK 4730 and NK 5252.
