Abstract
Before proceeding to the description of the phenomena of solar activity (SA), it is necessary at least briefly to get acquainted with the structure and physical properties of the outermost layers of the Sun. It is there that the main events take place—spots and torches are born and disintegrate, granules, filaments, prominences and coronal holes are formed, solar flares and coronal mass ejections (CME) occur, the solar wind is formed, magnetic clouds, shock waves are produced, etc. As a characteristic of the SA level, data on the number of spots in the photosphere are usually used. The spots contain the necessary supply of magnetic energy, and its changes over time give rise to the main SA phenomena. Not all of these active formations and phenomena are described below with the same completeness. Some additional details will be provided in subsequent chapters and in basic references.
We live in a solar corona.
