This paper represents the work of several years of observation of CTA102 with both single dish telescopes and interferometric arrays, covering wavelengths from 1.2cm to 1.3mm. The resolution of the maps covers an order of magnitude from 0.5mas to 50µas. The images presented demonstrate the rapid structural changes in this source. These rapid structural changes correlates with the outbursts seen in the total flux, turnover frequency and in the spectral index. We have calculated the Brightness Temperatures of the components (T_B) directly from the determined component sizes and also using the logarithmic variability amplitudes and timescales to calculate the T_Bs. Both the methods yielded measurements of source frame T_Bs no higher than ∼a few x10¹²K. We find that the observed average proper motion is ∼0.4±0.07mas/yr, which corresponds to an apparent transverse velocity of 11±2c.
