Magnetic loop-like features associated with the burst studied here. Left: sub-FOV of the SuFI map from Fig. 2 showing the loops. A few of the traced structures are highlighted with solid lines. Right: distribution of widths of selected loops along their length. The distribution shows the full width at half maximum of Gaussian fits to the intensity profile across a given loop at each position along the loop. The dashed and solid vertical lines respectively denote twice the pixel scale and diffraction limited spatial resolution of SuFI at 3968 Å. See Sect. 5 for details.
