The following improved orbital elements, by S. Nakano, are from 161 observations 2003 to 2022. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.79 arc second. The comet has passed 0.12 AU from Saturn on 1938 Jan. and 0.50 AU from Jupiter on 1947 June. Also comet passed 0.73 AU from Saturn on 1997 Sept. 10 and 0.81 AU from Jupiter on 2002 Sept. 3 UT.
