Flow past a circular cylinder started impulsively into radial vibration is investigated by visualizing the flow patterns by smoke release and by analyzing qualitatively (flow topology) and quantitatively (PIV and anemometry measurements) the corresponding images. The considered Reynolds numbers range corresponds to the subcritical regime (10 000
