Nakano Note (Nakano wa Kangaeru noda) NK 5358 C/2024 T3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 57 observations 2024 Sept. 8 to Dec. 9. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.48 arc second. The comet will pass 1.98 AU from Jupiter on 2025 Aug. 23 UT. See an orbit in CBET 5461. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 15.25053 +/- 0.04546 (m.e.)
