Abstract
A grazing incidence spectrograph launched in a Black Brant rocket August 30, 1973, at White Sands Missile Range obtained high spectral resolution data of the solar radiation between 200 and 700 A. Absolute intensities and profiles of the brighter lines in this spectral region were measured. Results for the He I 584-A and He II 304-A lines are presented. For the He I 584-A line the full width at half intensity is 0.08 A, and the intensity for the solar disk is 1.3 × 109 photons cm−2 s−1. For the 304-A He II line these values are 0.12 A and 6.3 × 109 photons cm−2 s−1, respectively.
