Abstract

A massive two-ribbon flare and its source magnetic field region were well captured by the Solar Optical Telescope (SOT) on board Hinode in the Ca n H spectral line and by the Spectro-Polarimeter of SOT, respectively. Using the high-resolution Hinode data sets, we compare the spatial distribution of the local magnetic reconnection rate and the energy release rate along the ribbons with that of G-band kernels that serve as a proxy for the primary energy release. The G-band kernels spatially coincide with the maximum of both modeled quantities, which gives strong support for the reconnection model. We also investigate the magnitude scaling correlation between the ribbon separation speed Vr. and magnetic field strength Bn at four 2 minute time bins around the maximum phase of the flare. It is found that Vr is weakly and negatively correlated with Bn. An empirical relation of Vr œ Bn-0.15 is obtained at the flare peak time with an correlation coefficient ̃-0.33. The correlation is weaker at other time bins.
