Solar Flare Location on the Extended Arc of Magnetic Lines with Increased Current Density, Obtained by Analyzing the Results of MHD Simulation

The appearance of extended surface of magnetic lines with increased current density (extended current sheet) in solar corona can solve the problem of the coincidence of the positions of flares found from the results of MHD simulation with the observed positions of flares.The compare of magnetic configuration near such a surface with observed flare emission show that flare energy release can occur not in the position of current density maximum, but in the place, were the current density is rather large and where the magnetic field configuration promote the flare instability development.For more convenient search of flare positions to study the solar flare mechanism, it will be better to modernize the existing graphical system for searching for flare positions taking into account obtained results about location of flare instability.
