  This paper demonstrates that intermittent magnetic field fluctuations in the
plasma sheet exhibit transitory, localized, and multi-scale features. We
propose a multifractal based algorithm, which quantifies intermittence on the
basis of the statistical distribution of the 'strength of burstiness',
estimated within a sliding window. Interesting multi-scale phenomena observed
by the Cluster spacecraft include large scale motion of the current sheet and
bursty bulk flow associated turbulence, interpreted as a cross-scale coupling
(CSC) process.
