Nakano Note (Nakano wa Kangaeru noda) NK 5317 P/2024 R1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 39 observations 2024 June 3 to Sept. 30. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.12 arc second. See an orbit in CBET 5441. Epoch = 2024 June 19.0 TT T = 2024 June 15.65879 +/- 0.00158 (m.e.)
