Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 141 observations 1998 Nov. 25 to 1999 Sept. 13, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.54 arc seconds. Epoch = 1998 Sept. 24.0 TT JDT = 2451080.5 T = 1998 Oct. 6.73963 +/- 0.00919 (m.e.)
