We present multiwavelength continuum light curves for the active galaxies 3C-120, Mrk 79, and Mrk 704 spanning the period March 2001 to May 2007. All CCD observations were made with the SARA 0.9-m telescope at Kitt Peak. Variations of several tenths of a magnitude are observed for all three objects; Mrk 79 exhibits a steady decrease in brightness over the past four years. Newly-derived V magnitudes and B-V, V-R, and R-I color indices are also presented for comparison stars within the field of each galaxy.
This work was funded by the National Science Foundation (grant AST-0552798) and the Department of Defense ASSURE (Awards to Stimulate and Support Undergraduate Research) program, and by a research grant from Valdosta State University.
