Chromosphere
In space and astronautical engineering, the chromosphere is a layer of the Sun's atmosphere that is located just above the photosphere and below the corona. It is characterized by a reddish glow that is visible during a total solar eclipse. The temperature of the chromosphere increases with height, and it is the site of many important physical processes, including the acceleration of the solar wind and the generation of ultraviolet radiation. The chromosphere is also the source of many of the Sun's most spectacular phenomena, including solar flares and coronal mass ejections.
