EUV observations of solar corona in the SPIRIT experiment on board the CORONAS-F satellite
Abstract
Images of solar corona up to 5 solar radius were obtained for the first time in resonance lines of E V spectral bands in the SPIRIT experiment on board theU CORONAS-F satellite launched 31 July 2001. Observations were made by: (1) two telescope/coronographs for narrow spectral bands at 175 A (FeX-XI) and at 304 A (HeII+SiIX) equiped with an "artificial Moon" (Diameter ~ 45 arc min) and with the mechanism for re-orientation of the field of view (50 arc min) in the limits of +/-2 degrees, (2) the slitless imaging spectroheliograph at 304 A . An examples of images are given for a quiet corona and in the presence of active phenomena: flares, CME, etc. The data obtained are important for modelling of solar wind acceleration, CME and other active phenomena in solar corona.
