Abstract
IN December 1973, during observations from the space observatory Orion 2 on Soyuz 13, three spectrograms of Capella (α Aur, GO III, mv=0.2) were obtained in the wavelength region 2,000–3,000 Å. The spectrograms were made by a wide-angle meniscus telescope of the Cassesgrain system, with an aperture diameter of 240 mm, an equivalent focal length of 1,000 mm, and a 4-grade quartz prism objective. The dispersion of the spectrograph was 170, 280 and 550 Å mm−1, at wavelengths of 2,000, 2,500 and 3,000 Å, respectively.
