A new searching algorithm to find voids in high resolution magnetograms is described. This algorithm permits the investigation of spatially intermittent nature of magnetic field emerging when solar surface is observed at high spatial resolution. Actually, at these small scales, the connected patterns, forming magnetic network, show aligned or clustered magnetic features producing a highly branched and fractal pattern embodying magnetic elements. High resolution Hinode/SOT and SDO magnetograms confirmed the presence of multiscale underdense (voids) magnetic regions. Preliminary Void Probability Distribution (VPD), measured in such high-resolution magnetograms, are presented and briefly discussed.

Abstract
A new searching algorithm to find voids in high resolution magnetograms is described. This algorithm permits the investigation of spatially intermittent nature of magnetic field emerging when solar surface is observed at high spatial resolution. Actually, at these small scales, the connected patterns, forming magnetic network, show aligned or clustered magnetic features producing a highly branched and fractal pattern embodying magnetic elements. High resolution Hinode/SOT and SDO magnetograms confirmed the presence of multiscale underdense (voids) magnetic regions. Preliminary Void Probability Distribution (VPD), measured in such high-resolution magnetograms, are presented and briefly discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
