Snapshot of the online movie. From left to right, first image: continuum images with the time for the entire row indicated at the top of the first image. Second image: at a cutoff level of ±50 Mx cm⁻² followed by images in at a cutoff level of 140 Mx cm². Last image: obtained by subtracting the red lobe area in Stokes V from the blue lobe area. All images show contours of at a level of ±30 Mx cm⁻² in blue and red, respectively. The green contours correspond to the apparent transverse magnetic flux density with a cutoff at Mx cm⁻². The lines overlaid on top of the third image starting from t = 36.22 min correspond to the horizontal magnetic field direction obtained from the SIR inversions.
