Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 55 observations 2000 July 24 to 2001 Apr. 23, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.48 arc seconds. Epoch = 2001 July 30.0 TT JDT = 2452120.5 T = 2001 Aug. 4.77375 +/- 0.00187 (m.e.)
