Chromosphere

(middle layer of the Sun's atmosphere)

The Chromosphere is the layer of the Sun's Atmosphere outside the Photosphere and inside the solar transition region. It is about 2000 kilometer's deep and its density is a hundred millionth that of the Earth's atmosphere. The inner boundary is 6000K and the outer boundary is 35000K.

The Chromosphere is visible during a solar eclipse.
