Nakano Note (Nakano wa Kangaeru noda) NK 4525 102P/Shoemaker 1
The following improved orbital elements, by S. Nakano, are from 391 observations 2006 to 2021, 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 +/- 0.87 arc second. Residuals of re-observations on 2021 September were -17" for Right Ascension and +8" for Declination from the prediction in NK 3636 (= HICQ 2020/2021) with the delta-T correction = +0.03 day. See the previous orbits in NK 461, NK 511, NK 563, NK 632, NK 945 (= MPC 48382), NK 1150, NK 1356 (= YC 2521), NK 1924, NK 2482, NK 2553 with an orbit of 1999 appearance and NK 3636.
