Nakano Note (Nakano wa Kangaeru noda) NK 5519 C/2024 T3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 102 observations 2024 Sept. 8 to 2025 Dec. 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.52 arc second. The comet has passed 1.98 AU from Jupiter on 2025 Aug. 23 UT. 2025 December observations show the residuals of -8" for Right Ascension and +3" for Declination from an orbit in NK 5387. See the previous orbits in CBET 5461, NK 5358 and NK 5387. Epoch = 2025 Mar. 26.0 TT T = 2025 Mar. 15.26166 +/- 0.00164 (m.e.)
