軌道要素The following improved orbital elements by Kenji Muraoka, are from 57 observations 1992 Apr. 9 to 2001 Mar. 25, perturbations by 9 Plantes, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.78 arc seconds. Epoch = 2001 Feb. 20.0 TT JDT = 2451960.5 T = 2001 Feb. 7.82229 +/- 0.01064 (m.e.)
