Nakano Note (Nakano wa Kangaeru noda) NK 4132 C/2020 F2 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 244 observations 2019 May 27 to 2020 June 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second. The comet has passed 7.78 AU from Neptune on 2006 Mar. 9 and 2.89 AU from Saturn on 2018 Mar. 12 UT. Also comet will pass 5.02 AU from Uranus on 2033 Oct. 10 UT.
