Abstract:

We present an update on the SARA Consortium, including the status of the two current telescopes and the possible addition of a telescope in the Canary Islands. We will then present a summary of the 15 project to study micro-variability in Blazars. The culmination of that study is a model for Blazar Micro-variability where the rapid, low amplitude fluctuations are the result of a shock passing through a turbulent section of the relativistic jet. As the shock encounters the turbulent cells, the plasma in the cells is accelerated and emit a pulse of Synchrotron emission. We show several well sampled micro-variability curves de-convolved and our model applied to determine the distribution of cell sizes and other physical parameters of of the turbulent flow.
