%X We present an optical intraday variability &#40;IDV&#41; study of S5 0716+714 carried out over 52 nights. The source showed detectable variations &#40;&#62;0.05 mag&#41; in 80% of the nights. Typical variation rates of 0.02 mag/hour have been found to last on average 4 hours, with the average rising rate faster than the decreasing one. A maximum rising rate of 0.16 mag/hour has been observed. If the luminosity variation is due to jittering in the jet direction, a comoving d&#952;/dt rate of &sim;100 arcsec/hour is required, assuming for the jet &#952; &sim; 7&#176; and &Gamma; &sim; 14.
