✦ Synopsis

X-ray spectra of solar flares in the spectral range from 8.5 A to ~ 16 A. have been obtained from a Naval Research Laboratory crystal spectrometer flown on the sixth Orbiting Solar Observatory (OSO-6). A list of emission features is presented and tentative identifications of some of the features are suggested. The time-behavior of the emission lines during flares is discussed, and the possibility of determining electron densities in flare plasmas using density sensitive lines of highly ionized iron is considered. Approximate calculations are performed for a density sensitive line of Fe xxii.
