Nakano Note (Nakano wa Kangaeru noda) NK 5315 P/2024 O2 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 54 observations 2024 June 30 to Sept. 30. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.18 arc second. The comet will pass 0.74 AU from Saturn on 2039 Apr. 8 and 1.78 AU from Jupiter on 2041 June 1 UT. See an orbit in CBET 5428. Epoch = 2024 May 10.0 TT T = 2024 Apr. 20.13934 +/- 0.02844 (m.e.)
