Nakano Note (Nakano wa Kangaeru noda) NK 5411 P/2017 FL36 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 27 observations 2017 Feb. 23 to Apr. 1. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.40 arc second. See an orbit in CBET 5551 (same orbit). Epoch = 2015 June 27.0 TT T = 2015 June 27.29651 +/- 0.60300 (m.e.)
