軌道要素The following improved orbital elements by Kenji Muraoka, are from 196 observations 1998 May 20 to Aug. 5, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.70 arc seconds. Epoch = 1998 May 27.0 TT JDT = 2450960.5 T = 1998 May 8.61890 +/- 0.00016 (m.e.)
