We fulfilled and reduced observations using following telescopes: VTT, THEMIS (European Northern Observatory, Spain), ATSU-26 (peak Terskol, Russian), GST AO KGU (Kiev). We measured radial velocities in the photosphere and chromosphere of the active region NOAA 11024 (new 24-cycle of the solar activity) and developed a preliminary models of the flare. We analyzed the dependence of convective motions on magnetic field strengths of the solar active region. The 3D modeling of the polarized radiation and spectropolarimetric observations showed that the small-scale magnetic field has to be equal 180 G and 130 G in the photosphere and the temperature minimum region, respectively. We found that magnetic field of the Sun as the star and variations of the sunspot magnetic field index correlates with 4-years delay. We got that dumping of the low degree p-modes by magnetic activity prevails in the lowest photospheric layers. We reconstructed the solar horizontal telescope ATSU-5 with the double monochromator and started test observations of solar spectral lines.
