Long-term optical behavior of 114 extragalactic sources

Abstract

Photographic observations of over 200 quasars and related objects have been obtained at the Rosemary Hill Observatory since 1968. Twenty that are optically violent variables were reported on by Pollock et al. (1979). This paper presents data for 114 less active sources, 58 of which exhibit optical variations at a confidence level of 95% or greater. Light curves are given for the 26 most active sources. In addition, the overall monitoring program at the Observatory is reviewed, and information on the status of 206 objects is provided.
