Abstract

Where does the primary energy release take place in solar flares? Although this is a very fundamental question, no clear observational result had been achieved yet. Hard X-ray imaging observations of solar flares give us hints to answer this question. Actually a new type of hard X-ray source, which may be a very important hint, was observed with the Hard X-ray Telescope (HXT) on board Yohkoh. We summarize the characteristics of this hard X-ray source and other related observational results below.
