Notes. The location is in helio-projective longitude (arcsec) and defined at the start time of the observation. The age of the AR is determined as the time from the emergence of the AR based on the AIA 193 Å images and HMI magnetographs. The magnetic field flux (Φ) is calculated only for the pixels above noise level |B|> 10 G. ( * )The location corresponds to the centre of the field-of-view at the start of the observation. Figures 3–6 show the field-of-view at the middle of the observation duration. ( * *)The average magnetic strength is calculated only for the pixels above |B|> 100 G to focus only on the core of the AR. ( * * * )The area of the AR is defined as the region where |B|> 100 G.
