Fig. 9


Photospheric magnetic flux cancellation/disappearance near the polarity inversion line. The images of the time sequence correspond to the LOS magnetograms (left), continuum intensity (middle), and dopplergrams (right) for the region marked by the dashed grey square labelled “2” in Fig. 6. The green (yellow) circle encloses a positive (negative) magnetic patch outlined in violet (turquoise). The magnetograms, continuum intensity, and dopplergrams have been scaled between ±1000 G, 0.1–1.05 IQS, and ±1.5 km s-1, respectively. The violet and turquoise contours enclose fields greater than 80 and 50 G, respectively, and have been enhanced by a factor of six for clarity. The white contour in the left column (black in Cols. 2–3) outlines a region of previous flux emergence where the flux also decreases in the time before the flares.
