EUV and Soft X-ray studies of the solar corona under the CORONAS space project
The active phenomena in the solar corona during the last 22nd and 23d solar cycles were studied with the new generation solar imaging instruments developed in the Lebedev Physical Institute (Moscow) under the PHOBOS and CORONAS space projects: the TEREK telescope (1988), the modified TEREK telescope and the RES spectroheliograph (1994) and the SPIRIT complex (2001-2005). The observations by the method of full Sun imaging spectroscopy in the Xray/EUV spectral interval 8.42 33s A has allowed to get temperature slices of the solar plasma in the wide temperature range from 0.02 to 20 MK. The most important results of these experiments include the discovery and study of new class of the long living hot coronal objects seen in the MgXII ion line, the diagnostics of the hot solar plasma (5-20 MK) from the Fe, Mg, Si, Ca ion line heliograms, the study of CME-related dimmings and other eruption phenomena by simultaneous observations in Fe IX-XI 175 and He 11 304 (A) bands, the observations of the solar corona at the distances up to 5R⊙ with the SPIRIT EUV telescope-coronagraph. These studies will be continued with the new TESIS telescope/spectroheliograph aboard the next CORONASPHOTON satellite planned for the launch in the end of 2008.
