英文摘要	The M4.0/SF flare on 17 March 2002 is a good example of the early observations with RHESSI. We present hard X-ray images, light curves and energy spectra of individual hard X-ray sources, the spatial relationship between the hard X-ray sources and the Ha emission regions, and comparisons of light curves observed by RHESSI and GOES. We found that the picture exhibited by RHESSI is consistent with the general cartoon of a solar flare. In particular, we showed that the hard X-ray image spectra could be explained by a power-law electron beam with a lower energy cutoff E-c. The derived E-c could be as high as 40 keV, larger than the usually value of 20 keV. (C) 2003 COSPAR. Published by Elsevier Ltd. All rights reserved.
