軌道要素The following improved orbital elements by Kenji Muraoka, are from 114 observations 1989 Oct. 26 to 1998 Mar. 9, perturbations by 9 Plantes, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.64 arc seconds. Epoch = 1997 Nov. 8.0 TT JDT = 2450760.5 T = 1997 Nov. 10.09264 +/- 0.00023 (m.e.)
