In solar-terrestrial terms, the layer of the solar atmosphere above the photosphere and beneath the transition region and the corona.

1868, coined by English astronomer Sir Joseph Norman Lockyer (1836-1920), from chromo-, from Greek khroma "color" (see chroma) + sphere. So called for its redness.

The part of the Sun's atmosphere just above the surface.

transparent layer of gas surrounding the photosphere (visible disc) of a star.

The thin (10 000 km) layer of relatively transparent gases, predominantly hydrogen and helium, above the photosphere and below the corona of the sun. It is best observed during total solar eclipse whe [..]

The middle layer of the solar atmosphere between the photosphere and the corona. The chromosphere is roughly 10,000 kilometers (6,200 miles) thick and is composed primarily of hydrogen. It varies in t [..]

Layer of the Sun's atmosphere located above the photosphere and below the corona. It is about 10 000 km deep and consists mainly of ionised hydrogen, helium and calcium. Its temperature ranges from 6000 °C at the photosphere boundary to 100 000 °C at the boundary with the corona. Its low density means it is usually only visible during a total [..]

(n) a gaseous layer of the sun's atmosphere (extending from the photosphere to the corona) that is visible during a total eclipse of the sun

The layer of gas above the visible surface (called the photosphere) of the sun. The temperature of this layer is between 6,000°C to 20,000°C.

a reddish layer in the Sun´s atmosphere, the transition between the photosphere and the corona

In solar-terrestrial terms, the layer of the solar atmosphere above the photosphere and beneath the transition region and the corona.

is a layer of the sun’s atmosphere. A gaseous envelope that surrounds the sun outside the photosphere from which large quantities of hydrogen and other gases erupt from.

The layer of the solar atmosphere above the photosphere and beneath the transition region and the corona. The chromosphere is the source of the strongest lines in the solar spectrum, including the Balmer alpha line of hydrogen and the H and K lines of calcium, and is the source of the red color often seen around the rim of the moon at total solar e [..]

The middle layer of the solar atmosphere between the photosphere and the corona. The chromosphere is roughly 10,000 kilometers (6,200 miles) thick and is composed primarily of hydrogen. It varies in temperature from below 10,000 Kelvin (18,000°F) to over 100,000 Kelvin (180,000°F).

Portion of the sun above the photosphere; consists of transparent ionized hydrogen and helium at 4000 to 40,000 ·C.

The irregular layer of the solar atmosphere that is located above the photosphere and beneath the corona. The temperature in the chromosphere rises from 6000° C to about 20,000° C. It is hotter than t [..]

A thin layer of relatively transparent gases above the photosphere of the sun. It is observed best during a total eclipse of the sun.

A thin layer of relatively transparent gases above the photosphere of the sun. It is observed best during a total eclipse of the sun.

A thin layer of relatively transparent

Region of stellar, particularly solar, atmosphere, above the photosphere and below the corona, characterized by a sudden increase in temperature. During a total eclipse of the Sun it shows up as a thin, bright pink layer, hence its name. The color is due primarily to the emission of hydrogen at 656.3 nanometers. On the Sun, it has a depth of approx [..]

In solar-terrestrial terms, the layer of the solar atmosphere above the photosphere and beneath the transition region and the corona.

The layer of the solar atmosphere above the photosphere

A thin layer of relatively transparent gases above the photosphere of the sun. It is observed best during a total eclipse of the sun.
