We have observed precise astrometric positions of the faint outer satellites of Jupiter J6ÈJ12 with the Kiso 1.05 m Schmidt telescope. The observational period is from 1990 November through 1992 March. We discuss the postÐt residuals after orbital improvement for our 1986È1990 observations and thereby emphasize the superiority of the intersatellite measures available only from wide-Ðeld Schmidt observations, which can cover all the satellites in a single plate.
