Periodic Variation of Solar Flare Index for the Last Solar Cycle (Cycle 24)

<div>MTM (upper panel) and Morlet wavelet (lower panel) analysis results for Northern Hemisphere FI data for the investigated time interval. White solid line in the wavelet scalogram shows the cone of influence (COI); black solid lines show the significant periodicities.</div>
