Nakano Note (Nakano wa Kangaeru noda) NK 5314 C/2024 N4 (Sarneczky)
The following improved orbital elements, by S. Nakano, are from 111 observations 2024 July 14 to Oct. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.44 arc second. The comet has passed 4.92 AU from Neptune on 2011 July 31 and will pass 3.17 AU from Jupiter on 2026 Dec. 2 UT. See an orbit in CBET 5421.
