軌道要素The following improved orbital elements by Kenji Muraoka, are from 616 observations 1999 Sept. 24 to 2000 Feb. 29, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.57 arc seconds. Epoch = 1999 Oct. 29.0 TT JDT = 2451480.5 T = 1999 Nov. 9.01313 +/- 0.00068 (m.e.)
