6 In the period from July 31, 2001 to December 6, 2005, CORONAS-F was observing the Sun and manifestations of solar activity in near-Earth space. Observations of solar activity

7 X-ray images of the Sun Simultaneous images in two spectral lines Images in various spectral lines corresponding to different temperature layers in the solar atmosphere Major active region and flare on the solar limb

8 CORONAS-F studied the location and morphology of numerous active phenomena on the Sun and their influence on the Earth in the period of powerful events near the maximum of 23 rd solar cycle. Morphology of the solar activity CORONAS-F

9 CORONAS-F discovered and observed many times a new class of the phenomena associated with the glow of high-temperature (5- 20 MK) plasma features in the solar corona. The structure and dynamics of these features that manifest one of the coronal heating mechanisms have been studied. New class phenomenon in the solar corona

10 Magnetic heating of the solar corona Sunspot number 7 keV 20 keV Quiet corona Heated corona New data were obtained concerning the coronal heating and spectra of X-rays affecting the Earth atmosphere. 10 keV

11 Global oscillations of the Sun CORONAS-F observed the modes of global oscillations of the Sun (p- modes). The dependence of the amplitude of these modes on the observational wavelength was established. SOHO

12 CORONAS-F studied solar flares - the most powerful explosive phenomena in the Solar System

13 Reconstruction of the magnetic field structure in the solar corona during the most powerful flare of September 7, CORONAS-F studied the fundamental processes underlying the nature of solar flares

14 keV keV keV keV Flare of October 29, 2003 Фон High-degree linear polarization of hard X-ray emission in the impulse phase of a powerful flare was recorded for the first time proving generation of accelerated particle beams. Beams TRACE

15 Spectroscopy of atomic processes in solar flares Spectral lines from atomic transitions 1s-np and 1s 2 – snp with high values of quantum number n

16 CORONAS-F studied the acceleration and nuclear processes in solar flares. Positrons from the decay of charged pions, solar gamma-emission from the decay of pions, and gamma-emission from the most powerful flares were recorded, and energy spectra of relativistic protons were measured up to the energy of 14 GeV. Nuclear gamma-lines from solar flares

17 CORONAS-F determined the contribution of UV emission from solar flares to the total solar emission flux affecting the Earth.
