N-S Asymmetry and Solar Cycle Distribution of Superactive Regions from 1976 to 2017
Universe, 2022 There were 51 superactive regions (SARs) during solar cycles (SCs) 21–24. We divided the SARs into SARs1, which produced extreme space weather events including ≥X5.0 flares, ground level events (GLEs), and super geomagnetic storms (SGSs, Dst < −250 nT ...
