Comparison between probability density functions of vertical electric current in solar active regions based on HMI/SDO and SOT/Hinode data

Zimovets, Ivan; Nechaeva, Alena; Sharykin, Ivan

Studying electric currents in solar active regions (AR) is an essential step in understanding solar activity in general and solar flares in particular. In this paper, we compare probability density functions of vertical electric current PDF(|jz|) in several active regions, using HMI/SDO and SOT/Hinode photospheric magnetic field data. We have esta…
