Abstract

A study of the relative timing of solar flare emissions at different wavelengths can provide valuable insights into the associated particle-acceleration mechanisms. We report here that the significant systematic differences between the times of occurrence of the peak intensities of microwave, hard X-ray and γ-ray line emissions, which were found in two impulsive flares on 7 and 21 June 1980 at 0312 and 0118 UT respectively, suggest that two kinds of acceleration take place successively within a few seconds.
