Abstract

Reconnection models of solar flares predict a systematic motion of hard X-ray (HXR) footpoints as magnetic energy is released and electrons are accelerated. While the correlation of the HXR flux with the apparent motion of the footpoints has previously been investigated, we derive and investigate for the first time the correlation between cumulative deposited energy at the footpoints and their separation. Providing excellent statistics, data from the Reuven Ramaty High Energy Solar Spectroscopic Imager of the 2002 July 23 flare are re-analyzed. The data show an excellent correlation for most of the time intervals. However, despite the good correlation, for some time ranges the derived amount of released magnetic energy is far too small to account for the energy in HXR-producing electrons.
