Nakano Note (Nakano wa Kangaeru noda) NK 5517 C/2024 G7 (ATLAS)
The following improved orbital elements, by S. Nakano, are from 79 observations 2024 Apr. 3 to 2025 Apr. 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.51 arc second. The comet has passed 1.94 AU from Uranus on 2015 Oct. 10 UT. See the previous orbits in CBET 5397 and NK 5272. Epoch = 2025 Feb. 14.0 TT T = 2025 Feb. 10.17785 +/- 0.03364 (m.e.)
