The following improved orbital elements, by S. Nakano, are from 105 observations 1995 Aug. 30 to Oct. 13. Perturbations by Mercury to Neptune and five minor planets were taken into account. The mean residual is +/- 0.77 arc second. See a same orbit on MPC 25932. Epoch = 1995 July 22.0 TT T = 1995 Aug. 2.72711 +/- 0.01204 (m.e.)
