Evolution of magnetic flux in solar active regions with strongest flares
Abstract
Using a series of vector magnetograms in Spaceweather HMI Active Region Patch (SHARP) format, for two hours before and after the solar flare, we calculated the magnetic flux using a nonlinear force-free field (NLFFF) method. We calculated the magnetic flux for 62 active regions that produced strongest flares in solar cycle 24 and identified five cases of evolution. We found that in most cases are increases in magnetic flux values during eruptions, this indicates that the onset of the eruption is correlated with the evolution of the magnetic flux.
