Description
Extensive monitoring is now available for a good sample of the brighter
quasars and BL Lacs. In some cases, lightcurves are well enough sampled
to permit stochastic modelling. The authors present here, a simple model
of the lightcurve of the prototype BL Lacertae object, BL Lac in terms
of a series of random events, each with rapid rise and exponential
decline. Whilst unable to explain very rapid "optically violent"
activity, it seems to provide a satisfactory fit to the long term trends
in the lightcurve.
