Zoomed CP maps of the box A (panels a–d), E (panels e–h), and D (panels i–n) from the SST/CRISP data at four representative times on September 4 and 5. The boxes are indicated in Fig. 6. All the CP maps are scaled to ±0.05 CP/I_c. The three red dashed lines in the first panel relevant to Box D indicate the three regions for which the magnetic flux evolution reported in Fig. 9 has been computed.
