Abstract: Galilean satellite astrometry has been derived from CCD photometry of nearly 200 eclipses in the shadow of Jupiter between the years 1990 and 2000. The root-mean-square differences as compared to predictions from J. H. Lieske's E5 ephemeris (1998, Astron. Astrophys. Suppl. 129, 205-217), expressed as along-track distances, are Io, 62 km; Europa, 267 km; Ganymede, 142 km; and Callisto, 146 km.
