2. Spatial Domain Temporal Domain Non-intermittent Network Intermittent Network What is the intermittency look like? time

3. Magnetic field in NOAA10930 from Hinode/SOT/FG intermittentExtended spatial/temporal intervals of low activity are intermittent with compact intervals of enhanced activity. spatialtemporalIntermittency presents in both spatial and temporal domains.

4. Intermittency can be derived from the Structure Functions 2D: x=(x1,x2) r u(x) u(x+r) x1 x2 1D: x = τ time u(t)u(t+τ) τ

5. Flatness function as an indicator of intermittency power law Fatness F( r ) is a constant for a non-intermittent variable and grows as a power law when scale r vanishes for an intermittent variable: Inertial range Scale, r F( r ) ~ r -κ-κ F( r ) =S ( r ) / (S ( r ) ) 6 3 2 The intermittency index κ κ Structure Functions Flatness Function

11. NOAA 10930: photospheric intermittency Hinode SOT/FG magnetogram To calculate intermittency in the photosphere, we utilized 2D magnetic field images derived with Hinode SOT/FG instrument. The covered time interval: 2006 Dec 8/12:00 UT to 2006 Dec 13/18:45 UT. Advantages: high resolution, high time cadence, uninterrupted measurements for several days

12. NOAA 10930: intermittency in the photosphere and corona

13. Conclusion Highly non-Gaussian, intermittent character of the magnetic fields in the both photosphere and corona; The data allow to suggest that intermittency is preliminary stored in the photosphere and then it is transported into the chromosphere/corona.

14. Conclusions The direct connection between the complex dynamics of the photosphere and corona may be suggested, and this connection requires a new kind of linking – one associated with the transfer of information between complex systems. This standpoint offers new possibilities for the photosphere / corona coupling.
