The electron temperature and density in the solar atmosphere in the region of emission of OV were obtained from rocket measurements of euv spectral line intensity ratios. The experimentally determined temperature was in very good agreement with the emission temperature of the spectral lines of OV predicted by theoretical values of the ionization equilibrium ratio n(OV)/ n(O). The experimental density, averaged over the entire solar disk, was also in good agreement with previous electron density measurements of the Harvard College Observatory. (auth)
