Abstract
Astrometric positions for the Galilean satellites are derived from hig h-precision timings of their jovian eclipses observed with CCD cameras between 1990 to 1993, and the positions are compared to Lieske's E-3 ephemeris. The root-mean-square (rms) ephemeris residuals for lo and C allisto were only 80 and 89 km, respectively; the rms residuals for Eu ropa and Ganymede were larger, 185 km and 142 km, with maximum residua ls of 340 km and 244 km, respectively.
