Evolution of solar active regions: Detecting the emergence of new magnetic field through multifractal segmentation

Golovko, A. A.; Salakhutdinova, I. I.

New emerging magnetic flux is identifed using a multifractal segmentation method used to investigate regularities in the evolution of active regions and activity complexes. The SOLIS, MDI SOHO, and SOT Hinode magnetograms were used. Observations of the active region NOAA 10488 on October 26-28, 2003 indicate considerable variability of areas of ne…
