New emission lines found in several flare spectra obtained with the Goddard grating spectrometer on the OSO-5 satellite, in 1969, have been listed by wavelength and relative intensity. These new lines, including several as strong as normal quiet-Sun lines, are extremely variable in intensity and have been assigned mainly to transitions of the type 2s - l2pk + in iron ions up to Fe xxiii. Subject headings: atomic processes - flares, solar - spectra, solar - spectra, ultraviolet
