Magnetic field-line reconnection is a universal plasma process responsiblefor the conversion of magnetic field energy to the plasma heating and chargedparticle acceleration. Solar flares and Earth's magnetospheric substorms aretwo most investigated dynamical systems where magnetic reconnection is believedto be responsible for global magnetic field reconfiguration and energization ofplasma populations. Such a reconfiguration includes formation of a long-livingcurrent systems connecting the primary energy release region and cold denseconductive plasma of photosphere/ionosphere. In both flares and substorms theevolution of this current system correlates with formation and dynamics ofenergetic particle fluxes. Our study is focused on this similarity betweenflares and substorms. Using a wide range of datasets available for flare andsubstorm investigations, we compare qualitatively dynamics of currents andenergetic particle fluxes for one flare and one substorm. We showed that thereis a clear correlation between energetic particle bursts (associated withenergy release due to magnetic reconnection) and magnetic fieldreconfiguration/formation of current system. We then discuss how datasets ofin-situ measurements in the magnetospheric substorm can help in interpretationof datasets gathered for the solar flare.
