Nakano Note (Nakano wa Kangaeru noda) NK 5356 C/2024 R4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 60 observations 2024 July 3 to Dec. 6. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.22 arc second. The comet has passed 2.33 AU from Saturn on 2024 Apr. 7 and will pass 2.74 AU from Jupiter on 2028 Oct. 28 UT. See an orbit in CBET 5450.
