Abstract

Improved positions for variable stars located south of the equator are being determined by  measuring the first-epoch plates of the Yale-San Juan astrometric survey. The new positions, referred to the system of the SRS, have an average standard error of 0.7 in both RA and Dec. Some of the differences between these new positions and those quoted in the General Catalog of Variable Stars (Kholopov et al. 1985) are as large as one degree. Variable stars having more than one name assigned to them are also identified.
