Chromosphere
The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep (approximating to, if a little less than, the diameter of the Earth).
Chromosphere
From LoveToKnow 1911
CHROMOSPHERE (from Gr. xpiepa, colour, and c4aipa, a sphere), in astronomy, the red-coloured envelope of the sun, outside of the photosphere.
Chromosphere
The chromosphere is the second most outer layer of the Sun. Several thousand kilometres thick, it resides above the photosphere and beneath the corona.

Chromosphere
The chromosphere is a narrow layer above the photosphere that raises in temperature with height. Normally, it can't be seen by the naked eye because the light from the photosphere of the Sun overpowers it.
Chromosphere
This entry contributed by Dana Romero
The layer of the Sun lying just above the photosphere.
The chromosphere is also home to spikes of gas called spicules that rise through it at the edges of the large convection cells that exist within the layer (so called supergranules).

The next layer up is the Chromosphere. Even though this layer is further from the surface of the Sun, the temperature of the chromosphere is greater than that of the photosphere, typically about 10,000 K.

When the new Moon covers up the photosphere during a total solar eclipse, you can see the pearly-white corona around the dark Moon.
Above the chromosphere lies the transition region, where the temperature increases rapidly on a distance of only around 100 km.

This is the one opportunity for humans to view the next, higher layer of the solar atmosphere, called the chromosphere. Immense plumes of hot gas propelled through the chromosphere appear as tiny luminous threads on the Sun's unraveling edge.
Above the photosphere lies a region called the chromosphere. It has this name because this layer of the Sun's atmosphere can be seen during the last moments before totality in a solar eclipse as a pinkish layer (hence color, or chromo).
In addition, there are two layers of gas above the photosphere called the chromosphere and the corona. Events which occur on the Sun include sunspots, solar flares, solar wind, and solar prominences.
A solar flare is a sudden intense brightening of a small part of the Sun's chromosphere in the vicinity of a plage or facula and often near a sunspot group. The flare develops in a few minutes and may last several hours.
The Sun's faint corona will be visible, and even the chromosphere, solar prominences, and possibly even a solar flare may be visible.
The chromosphere, which extends for several thousand kilometers above the photosphere, has a temperature near 30,000 K (about 54,000° F).
Above the photosphere is another layer of gas, about 2,000km thick, called the chromosphere. Its temperature is higher, with a typical value of 105K.
Its greater sensitivity allowed Jansen and Lockyer to photograph the spectral lines in the Sun's chromosphere and discover the element Helium. It was not isolated in a laboratory until 1895.
A magnetic storm is a temporary perturbation (disruption) of the Earth's magnetic field, caused by solar flares, which eject plasma from the Sun's chromosphere.

Astronomers describe different "layers" of our Sun based on what can be seen when looking at different colors (wavelengths) of light. The layers we can most easily see are the photosphere, chromosphere, and the corona.

Past indications of a planetary companion around Epsilon Eridani have been difficult to verify because the young star is "jittery" with a very active chromosphere.
