Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 357 observations 1998 May 28 to 1999 Aug. 12, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.62 arc seconds. Epoch = 1998 Aug. 15.0 TT JDT = 2451040.5 T = 1998 Aug. 13.17111 +/- 0.00055 (m.e.)
