Scientific paper

The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) is the first spacecraft with high-spectral-resolution germanium gamma-ray detectors to be dedicated to solar flare studies. We will report on RHESSI's first observation of a major gamma-ray line flare, the X4.8 limb flare of July 23, 2002. RHESSI observed nuclear de-excitation lines of Mg, Si, Ne, O, and C from this flare, plus the neutron-capture line at 2.223 MeV. There is evidence for redshifts and Doppler broadening of the de-excitation lines, as well as temporal variations of the line spectrum. We will discuss the implications of these observations for the spectrum, time variation, angular distribution, and composition of the accelerated ions and for the composition of the interaction region.
