Magnetic field evolution at the photospheric level. Panels a)f) show the LOS magnetic field evolution as seen with MDI. We have indicated with an arrow the location of a major negative sunspot around which a northern sunspot rotated from the northeast to the southwest. The ellipses indicate the approximate location of the flare and jet activity along those days. The images are derotated to Sun center and the size of the field of view (FOV) is 290 per 200′′. The images have been saturated below (above) 500 G (500 G). We added three contours to panel e) at ±50, ±100, and ±500 G in magenta (cyan) for positive (negative) values.
