The Chromosphere. Click on image for larger version. The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000&degC to about 20,000&degC. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).
Temperature. The temperature of the chromosphere ranges between 6,000 and 50,000 degrees Celsius. Unlike most objects in the solar system, the chromosphere actually increases in temperature as it moves away from the sun.he chromosphere is a layer of the sun that is 2,000-3 000 kilometers thick. Located above the photosphere, reddish glows can only be seen easily in a total solar eclipse when the photosphere is blocked by the moon.
