We present analysis of both the short-term optical and multiwavelength variability of CTA 102. In 2004, this object was observed in an intense optical flaring state. Extensive R-band microvariability observations were carried out during this high state. In 2005, we obtained several weeks of contemporaneous radio, optical, and X-ray observations of CTA 102. These observations recorded distinct flaring activity in all three wavebands. Subsequent analysis revealed that the X-ray, optical, and radio activity do not appear to be correlated. The shape of the observed SEDs suggest that both the synchrotron and inverse Compton processes may contribute to the X-ray emission. Our results are compared to other results on this object and with archival microvariability observations. It appears that more rapid, dramatic microvariability events occur when CTA 102 is in an elevated flux state. This research was supported in part by Research Program Enhancement funds from Georgia State University, by NASA, and by NSF.
