TFG evolution at three different times (top) following the granules with the horizontal flows after t = 1427 s (at 16:58:59 UT), after t = 3214 s (at 17:28:48 UT), and after t = 5001 s (at 17:58:33 UT) and superimposed NIRIS magnetic field (blue). Bottom: Evolution of the magnetic field (now in white). The magnetic field has been reversed for a better view of the MMFs. The two squares locate the TFG1 and TFG2 examples shown in more detail in Figs. 10 and 11. The FoV is 70″ × 70″ and the threshold of the magnetic field is 20 Gauss. The black or white lines in the diagonal are artifacts due to field rotation. Animation of the magnetic field in blue is provided in online movie Intb-paper.mp4.
