Four examples of magnetic field evolution around QSEBs. The four upper panels per sequence show Hα wing image cutouts at Δλ = −1 Å, the four lower panels corresponding Stokes V/I_cont maps obtained from CRISP spectropolarimetry in Fe i 6173 Å. These are averages over 6 wing positions at Δλ = ± 0.150, ± 0.105, and ± 0.070 Å from line center. Signals below 3σ_noise are put to 0 in the greyscaling, positive polarity is white with red contours, negative polarity is black with blue contours. The contour levels are at 0.2, 0.5, 1, and 2% polarization. The yellow cross at the center of each panel serves to guide inspection. a) and c) are from dataset 7 (μ = 0.73), b) and d) from dataset 8 (μ = 0.64). Animations of this figure are available in the on-line material. (Online movie.)
