Особенности поведения микроволнового излучения активных областей на Солнце перед корональными выбросами массы
Solar flares and coronal mass ejections (CME) are the most powerful manifestations of solar activity. Both phenomena associated with the evolution of the spatial structure of the magnetic field of active regions (AR). It is known that not all powerful flares accompanied by CME. In some cases, CME are observed, associated with very low intensity bursts. At the same time, the observational signs that determine the ability of AR to cause the eruption of matter from AR into the high layers of the solar corona are still not clear. This makes it difficult to understand the physical mechanism of eruption initiation (CME trigger). The purpose of this work is to search for observational signs of the onset of the eruptive process. For this, we conducted a comparative analysis of pre-flare and flare conditions for 6 flare events, accompanied by CME, and 5 events not accompanied by CME.
