Scientific paper

Results are discussed for photographic UBV observations of OJ 287 to determine whether its brightness changes are accompanied by variations in color. A total of 99 sets of observations were obtained over a three-year declining phase, and a few IR observations were also made. The results of the four-color observations are graphed together with least-squares parabolic curves fitted to the UBV observations through April 1974, and they reveal random short-term fluctuations of small amplitude superimposed on a general decline of about three magnitudes. Short- and long-term (U-B) and (B-V) color indices are computed, and all indicate no significant color trend during the three-magnitude decline.
