Nakano Note (Nakano wa Kangaeru noda) NK 3590 C/2017 M5 (TOTAS)

The following improved orbital elements, by S. Nakano, are from 152 observations 2016 May 30 to 2018 May 15. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.54 arc second. The comet has passed 1.51 AU from Saturn on 2015 Mar. 25 and will pass 2.38 AU from Uranus on 2026 Sept. 4 UT. See the previous orbits in NK 3470 (= HICQ 2018) and NK 3560.
