The following improved orbital elements, 06F1-001 by S. Nakano, 06F1-000 are from 26 observations 1991 Aug. 3 to 1992 Oct. 9. Perturbations by all nine planets and five minor planets were taken into account. The mean residual is +/- 0.75 arc second. 06F1-001 Epoch = 06F1-000 1992 May 18.0 06F1-001 TT 06F1-000 06F1-001 T = 06F1-000 1992 May 3.44559 +/- 0.00184 06F1-001 (m.e.)
