軌道要素The following improved orbital elements, by Kenji Muraoka are from 352 observations 1998 Apr. 26 to July 20, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.68 arc seconds. Epoch = 1998 Apr. 17.0 TT JDT = 2450920.5 T = 1998 Apr. 14.42482 +/- 0.00074 (m.e.)
