Nakano Note (Nakano wa Kangaeru noda) NK 5347 C/2024 B1 (Lemmon)
The following improved orbital elements, by S. Nakano, are from 123 observations 2023 Oct. 13 to 2024 Nov. 28. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.64 arc second. 2024 November observations show the residuals of -6" for Right Ascension and +8" for Declination from an orbit in NK 5302. The comet has passed 2.65 AU from Jupiter on 2024 Mar. 20 UT. See the previous orbits in NK 5184 (= CBET 5344) and NK 5302. Epoch = 2024 Oct. 17.0 TT T = 2024 Oct. 7.70005 +/- 0.00062 (m.e.)
