A. ; Canfield, R. C. ; Acton, L. W. ; Kiplinger, A. L. Abstract The solar flare of 15:22 UT on June 24, 1980 is analyzed using simultaneous observations in hard X-rays, soft X-rays, and H-alpha line profiles obtained from instruments aboard the Solar Maximum Mission and ground-based instruments. The theoretical H-alpha profiles of Canfield, Gunkler, and Ricchiazzi (1984) are used to analyze the H-alpha data, and the work of Hummer and Rybicki (1968) is used to provide qualitative velocity information. The soft X-ray data are employed to obtain coronal measurements of parameters of interest, while the flux and spectrum of the hard X-rays are used to calculate the peak power of nonthermal electrons. Various flare phenomena are studied, including heating of the chromosphere by nonthermal electrons, enhanced coronal pressure, enhanced thermal conduction, chromospheric evaporation and mass motion. It is shown that the observations strongly suggest a scenario in which two large magnetic loop systems interact to provide the flare energy.
