Panel a): normalized time series of the magnetic field strength (maximum values) obtained from the SDO/HMI magnetograms of the large unipolar sunspot in the active region NOAA 11216. The active region field-of-view is [100″ × 100″]. The active region center coordinates are [− 239″ × − 198″] obtained at 20:00 UT on 2011 May 20. The time series starts at 00:00 UT on 2011 May 20. Panel b): wavelet power spectrum of the time series. Panel c): global wavelet spectrum with a significance level of 95%.
