4 CORONAS-F Satellite

5 Время существования: July31, 2001 - December 6 2005 (4 года и 4 месяца) The Height of the Orbit ~ 500 км Orbital Period ~ 95 мин Inclination ~83° Investigations of the 23 rd Solar Cycle on CORONAS Satellites Wolf Numbers  **************  CORONAS-F  *********  CORONAS-I 1996 2001 2007

6 X-Ray Imaging of the Sun Simultaneous images in two spectral lines Images in the different spectral lines, corresponding to the various layers of the solar atmosphere Powerful active region and flare on the solar limb

7 Morphology of the solar activity Powerful flares and ejections on November 26, 2003

8 SOHO/LASCO New phenomena in the solar corona Plasma formations in solar corona with temperatures up to 20 MK. Coronal Mass Ejections CORONAS-F/SPIRIT

9 Magnetic Heating of the Solar Corona The sunspot number  7 keV 20 keV  Quit corona Heated corona New data on the heating of the solar corona and on the spectra of X-ray emission influencing on the Earth atmosphere.  10 keV

10 Global Oscillation of the Sun Global oscillations of the Sun have been studied and the dependence of its amplitude from the wavelength of observation have been established.

11 Solar Flares – the most powerful explosive phenomena in Solar system

12 The reconstruction of the magnetic field structure in the solar corona during the most powerful flare on September 7, 2005. Fundamental processes of the solar flare nature

13 60-100 keV 40-60 keV 20-40 keV 15-40 keV Flare on October 29, 2003. Background Linear polarization of the hard X-ray emission in solar flares and generation of the beams of accelerated particles. beams

14 Atomic processes in solar flares For the first time the spectral lines of atomic transitions of solar plasma ions 1s-np и 1s 2 – snp with high value of quantum number n have been recorded Some new spectral lines in solar flares have been detected

15 The accelerating and nuclear processes in solar flares have been studied. For the first time the positrons from decay of the charged peonies have been recorded. A chemical composition of the solar atmosphere, gamma emission from the decay of the peonies, nuclear gamma lines from the most powerful flare, the spectra of relativistic protons up to 14 GeV have been studied. Nuclear gamma lines in solar flares

16 The contribution of the solar flare UV emission into the total solar emission flux influencing on the Earth.
