Snapshots of the photospheric magnetic field in the AR nest from HMI and PHI. The snapshots are chosen to match the EUV observations from Fig. 3 best. The measurements are projected into Carrington coordinates. Solar flares observed by GOES or STIX within three days of each snapshot are shown with crosses that are coloured by flare class. When available, the NOAA AR numbers are annotated. The arrows labelled (a) to (o) highlight flux emergence events between each snapshot.
