Nakano Note (Nakano wa Kangaeru noda) NK 5481 A/2025 P1
The following improved orbital elements, by S. Nakano, are from 52 observations 2025 Jan. 10 to Aug. 25. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.34 arc second. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 30.53445 +/- 0.00132 (m.e.)
