Restructuring of the Solar Magnetic Fields and Flare Activity Centers in Cycle 24     

A. V. Borovik  A. V. Mordvinov  E. M. Golubeva  A. A. Zhdanov 《Astronomy Reports》2020,64(6):540-546

The development of the solar magnetic activity in cycle 24 has been analyzed. It has been shown that the significant north–south asymmetry of magnetic activity was accompanied by the asynchronous reorganization of solar magnetic fields in the northern and southern hemispheres. The formation of unipolar magnetic regions after the decay of activity centers has been studied. The meridional transport of unipolar magnetic regions leading to changes in the zonal structure of the solar magnetic field has been shown. Long-lived centers of flare activity have been found to exist during the periods of magnetic field restructuring. The spatiotemporal analysis of the flare ensemble making it possible to diagnose non-stationary processes in the solar atmosphere has been shown.  相似文献
