The OSO-7 data on solar x-ray bursts have been used in several studies of solar flares. These studies have emphasized the correlation between X-ray emissions and phenomena observed at other wavelengths. A study of flares occurring beyond the solar limb has helped to determine the vertical extent of flare X-ray emission. This investigation also showed that the hot X-ray plasma cools predominantly by conduction, lending support to theories in which H alpha and other optical emissions obtain energy in this fashion. Another study determined the basic parameters of hard X-ray spectra as a support for detailed comparison with solar microwave emission.
