The object CTA 102, a low-frequency variable quasar, was observed with a VLBI Global Array in 1987.5 and 1988.5 at 5.0 GHz. The structure is complex, with three compact components along a line at PA = 157 deg, and several extended, ill-defined components east of the southernmost compact component. The components have no detectable relative motions, with mu less than 0.5 mas/yr along the main axis. This contrasts with the observation reported by Baath (1987), who found mu = 0.65 + or - 0.15 mas/yr at 932 MHz, which is exceptionally high. The new upper limit allows CTA 102 to be in the normal range of superluminal sources.
