High spectral resolution solar flare spectra have been recorded by four Bragg crystal spectrometers flown by the Naval Research Laboratory on a spacecraft launched 1979 February 24 by the Air Force. The wavelength ranges discussed in the Letter are 1.82--1.97 A, 2.98--3.07 A, and 3.14--3.24 A. Electron temperatures ranging between 12 x 10/sup 6/ K and 30 x 10/sup 6/ K are derived from dielectronic satellite to resonance line ratios for an X9 flare that occurred on 1979 March 25. Nonthermal motions varying between about 70 and 160 km s/sup -1/ are derived from line profiles. Equilibrium conditions in the plasma are investigated using lithium-like satellite lines excited by electron impact excitation. Emission measures of about 5 x 10/sup 50/ cm/sup -3/ are determined for the times of maximum X-ray flux.
