Abstract: The astrometric positions of eight irregular Jovian satellites are given for the oppositions of the planet from 1995 to 1999. These positions were measured on 204 CCD frames obtained at the Cassegrain focus of a 1.6 m reflector. They are compared with the theoretically calculated positions from JPL Development Ephemeris. The observed minus-calculated standard deviation for all observations of the eight satellites are sigma_alpha= 0.071 arcsec and sigma_delta= 0.052 arcsec. The USNO-A2.0 catalog was used for the astrometric calibration.
