Fig. 2


Photospheric flux evolution in AR 10977 as determined with SOHO/MDI magnetograms. The data are displayed between  ± 100 Gauss. The yellow contour shows the area within which the negative flux is measured during the main flux cancellation episode. In a similar way, the total unsigned flux of the region is determined by fitting a countour around the whole active region.
