Sažetak
A well-observed GOES M3.9 two-ribbon flare was analysed in order to derive the local reconnection rate (coronal electric field) and the global reconnection rate (magnetic flux change rate), as well as the energy release rate (Poynting flux) in a two-ribbon flare from chromospheric/photospheric observations, using TRACE 1600 Å , Kanzelhöhe Hα , SOHO/MDI, and RHESSI hard X-ray (HXR) data. We found good temporal correlations between the derived time profiles and observed HXR flux. Furthermore, it was confirmed that equal shares of positive and negative magnetic flux participated in the reconnection process. The findings indicate that the 2D reconnection model is applicable to the analysed flare.
