Time series of the total unsigned non-neutralized electric currents, I_NN, tot (black). Overplotted are also the total unsigned magnetic flux Φ (solid pink) and the magnetic flux of the non-neutralized partitions Φ_NN, tot (dotted pink). Green, yellow, and red dots indicate occurrences of C-, M-, and X-class flares, provided by NOAA SWPC. The time axis is in days, starting on 2 May 20224.
