High resolution profiles of the Mg xn 8.42 A line in the solar X-ray spectrum were recorded from the Intercosmos 7 satellite. The Mg xaI line intensity provides a sensitive indicator of the hot plasma content (T > 3 • 106K) in coronal condensations and X-ray flare volumes. The ratio of the line inte
An improved X-ray polarimeter is briefly described and preliminary results of the measurements carried out on the satellite 'Intercosmos-7' are presented. One flare with considerable polarization (P~> 16%) was observed on 1972 August 4. Two other flares with rather low polarization (P ~ 4 %; P/> 2 %
