V823 Cas is an interesting variable star that exhibits multi-periodic behavior. We completed multicolor CCD photometry of V823 Cas over nine nights between Sep 2011 and Feb 2012 using the 0.35 m robotic telescope at The College of Idaho. Preliminary frequency analysis, based on over 1000 observations, shows a complicated light curve with differential magnitude variations up to 0.6 in V and B. In addition, our investigation indicates first and second pulsation mode periods of 0.6643 and 0.5129 days, respectively. A third, less prominent mode with a period of 0.4119 days was also found. Overtone pulsation modes appear to exist as well, but will require additional observations to investigate more fully.
