Description:
    This is the second paper based on the 408MHz monitoring program with
    the East-West arm of the Bologna interferometer. The monitoring
    concerned 125 radio sources measured approximately once a month for 15
    years. We present the summary of the variability analysis concerning
    all the sample and the monitoring data, not yet published, of the
    variable sources.
