Four separate high-speed photometry runs were made on 4C 29.45 during an optical outburst. They indicate rapid brightness variations on the order of 0.02d or less. Evidence for rapid optical variations is presented along with estimates of the degrees of certainty which exist. Further studies of objects of this type are required before a definitive model can be adopted. Several viable theoretical descriptions of a quasar involve a very massive black hole surrounded by an accretion disk. These theories can explain the short time variability reported here with a realistic choice of model parameters.
