Description
Results are presented from simultaneous optical and radio observations of the BL Lacertae object 0716 + 714. During a 4-week period of continuous monitoring the source displayed in both wavelength regimes a transition between states of fast and slow variability with a change of the typical variability time scale from about 1 day to about 7 days. The simultaneous transition is interpreted as evidence for intrinsic source variability, and some consequences for the optical and radio emission regions are discussed. 19 refs
