chromosphere
Sun's red atmosphere
The chromosphere is the layer of the sun's atmosphere just above the visible surface, appearing as a reddish glow during total solar eclipses.
The name reflects its color—Greek for "sphere of color." Between the photosphere below and the corona above, the chromosphere is where solar flares and prominences originate.
