We have analyzed the solar flare of 15:22 UT 1980 June 24 using simultaneous observations in hard X-rays, soft X-rays, and H..cap alpha.. line profiles. The X-ray observations were made with instruments aboard the Solar Maximum Mission satellite, and the H..cap alpha.. profiles were taken with a CCD detector at Sacramento Peak Observatory. We used the 1984 theoretical profiles of Canfield, Gunkler, and Ricchiazzi to analyze the H..cap alpha.. data. We studied various flare phenomena, including heating of the chromosphere by nonthermal electrons, enhanced coronal pressure, enhanced thermal conduction, chromospheric evaporation and mass motion. We find that we can make a consistent picture of the flare in terms of coronal and chromospheric processes.
