abstract: We report new results of investigations of the solar corona by the method of XUV imaging spectroscopy with the SPIRIT complex. The experiment is carried out aboard the CORONAS-F satellite launched in July, 2001. The main feature of the experiment is a simultaneous registration of solar images in 11 independent channels which allows studying full solar disk and over-limb structures in narrow spectral bands and monochromatic lines in spectral bands 8.41-8.43 ?, 177-207 ? and 280-335 ?. The investigation has been done during maximum and decay phases of 23rd cycle of solar activity and allow to study as extreme events like flares, coronal mass ejections (CME) associated phenomena and long duration events like development of coronal holes. Spectral diagnostics of some of this structures has been done.
