Photometric data for ten X-ray-selected quasistellar objects have been obtained from archival records of the Rosemary Hill Observatory. Reliable magnitudes were obtained for seven of the ten sources and six displayed optical variations significant at the 95 percent confidence level or greater. One source appeared to exhibit optically violent behavior. Light curves and photographic magnitudes are presented and discussed. 22 references.
