Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 136 observations 1998 Aug. 24 to Nov. 22, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.58 arc seconds. Epoch = 1998 July 6.0 TT JDT = 2451000.5 T = 1998 June 29.50742 +/- 0.00056 (m.e.)
