We present analysis of both the short-term optical and long-termmultiwavelength variability of CTA 102. In 2004, this object was observed in anintense optical flaring state. Extensive R-band microvariability observationswere carried out during this high state. In 2005, we obtained several weeks ofcontemporaneous radio, optical, and X-ray observations of CTA 102. Theseobservations recorded distinct flaring activity in all three wavebands.Subsequent analysis revealed that this object may appear redder when in abrighter optical state, and that the X-ray, optical, and radio activity do notappear to be correlated. The shape of the observed spectral energydistributions suggests that both synchrotron-related and external inverseCompton processes may contribute to the X-ray emission. Our results are alsocompared with other results on this object and archival microvariabilityobservations. It appears that more rapid, dramatic microvariability eventsoccur when CTA 102 is in an elevated optical flux state.
