Abstract A 7-yr photometric study of nearly 200 extragalactic radio sources has shown that their optical variability is a complex and many-faceted phenomenon. Twenty optically violent variables were discussed in a previous paper by McGimsey et al. (1975). In the present paper 64 less-active sources with well-established comparison sequences are discussed. Light curves and photometric data are given for the 23 objects exhibiting variations that are significant at the 95% confidence level. The variability data do not appear to show strong evolutionary effects.
