Description

I will review the observed variability of the low accretion
rate AGN in Brightest Cluster Galaxies (BCGs). Radio/sub-mm
monitoring of a sample of several dozen systems over the past decade
shows most systems have varied by >30% and many by factors of >2.
The implications of this variability, particularly in the sub-mm,
will be discussed.
