Astrometric Observations of Wide Southern Double Stars - II

Astrometric CCD observations have been made of wide (~3 to 60 arcsec) southern double stars selected from the Washington Double Star catalogue (WDS). Southern double stars have not been well studied in the past; typically they had not been measured since about 1930, and ~50% of them have been observed only once before our observations. Of the pairs measured ~80% show no evidence of motion since the last observation. This is Paper II in which we present the observations of 290 WDS stars in the approximate RA range 17^h 13^m to 07^h 30^m and in the declination range -70° to -60°. We suggest 412 companions for these 290 stars and list 29 (10%) pairs that have shown significant motion.
