Soft X-ray flux recorded by GOES between 19:00 UT and 23:40 UT (solid line). The dashed green line corresponds to its derivative. The dashed red line corresponds to the sum of parasitic positive magnetogram values found in patch A in the negative polarity umbra of the MDI magnetograms. The function was multiplied by a factor for the purpose of shifting the values into the plotting range. The blue dashed-dotted line is the number of multilobed Stokes V profiles observed with SOLIS and found in patch A again scaled to the plotting window. The vertical lines at the top of the figure signify the recording time of the magnetograms (a–i) displayed in Fig. 8.
