In the past two centuries, alert amateur and professional meteor astronomers have documented 35 outbursts of 17 individual meteor streams well enough to allow the construction of a homogeneous set of activity curves. These curves add to similar profiles of the annual streams in a previous paper (Paper I, See Cat. ). The activity curves, expressed in terms of Zenith Hourly Rates (ZHR), have a shape that is usually well described by: ZHR=ZHR(max)10^(-B|{lambda}{sun }-{lambda_{sun}_(max)}|)^. The steepness of the slopes varies from an exponent of B=7 to B=220 per degree of solar longitude, with a typical value of B=30.
