We present BVRI photometry of R Mon/NGC 2261. The brightness variations of this system have been well documented and are believed to be the direct result of dark bodies orbiting R Mon and casting shadows upon the nebula. The apparent movement of the shadow boundaries suggest outward motion similar in character to a rotating beam of light from a lighthouse playing on cloud banks at different distances. We describe preliminary results of a project to study R Mon/NGC 2261 using CCD imaging data obtained during the period 1985-1988. The time based color analysis allows us to study spatially the changes in the light intensity from the nebula near R Mon. We present photometry from a data set obtained on December 5, 1988.
