Six flat spectrum radio sources (two quasars and four BL Lac objects) were monitored simultaneously in the optical (R-band) and radio (6 and 11 cm) regimes with a time resolution of a few hours. In three of the BL Lac objects, intraday variability was detected in both significant variations in either domain. In all cases, the amplitudes of the optical variations were larger than those in the radio range; in 0954+65, the R-band amplitude reached about 100 percent within 20 hours. The variability is probably intrinsic to the sources. Models based on shock waves propagating in the pc-scale jet can explain the radio variations; the physical relation between optical and radio variability deserves clarification, however.
