Fig. 7


Top view of the photospheric map of the vertical current resulting from the NLFFF extrapolation from the HMI vector magnetogram (in greyscale). The colour scale ranges from 350 × 1.6 × 10-6 A m-2 to 600 × 1.6 × 10-6 A m-2. Red and green iso-contours correspond to positive and negative Blos = ± 40,250,750 G, respectively. The pink field lines correspond to the HFT related QSL field lines. The field of view for the magnetic field data is x = [580,650] ′′, y = [55,120] ′′ in the CEA projection frame. The field of view of the vertical current image is slightly larger.
