\caption{\label{tab:sum}Summary of the properties of flare or nonflare activity in AR~8210 for
the sunspot rotation and the fast moving polarity. The magnetic energy and the
magnetic helicity are global quantities therefore we just mention the
characteristic evolution  of both quantities before and after a flare
associated with BSEs. (SW = South-West)}
