Nakano Note (Nakano wa Kangaeru noda) NK 3619 C/2017 S3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 135 observations 2017 Aug. 17 to 2018 July 8. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.51 arc second. See the previous orbits in NK 3525, NK 3543, NK 3591, NK 3591A and an un-published orbit in HICQ 2018. Epoch = 2018 Aug. 30.0 TT T = 2018 Aug. 15.94720 +/- 0.00016 (m.e.)
