An atmosphere of rare matter, composed principally of incandescent hydrogen gas, surrounding the sun and enveloping the photosphere. Portions of the chromosphere are here and there thrown up into enormous tongues of flame.
An incandescent, transparent layer of gas, primarily hydrogen, several thousand miles in depth, lying above and surrounding the photosphere of a star, such as the sun, but distinctly separate from the corona.
the gases of the solar chromosphere appear to be hotter than the photospheric gases which lie below them. In the chromospheric region temperature rises abruptly by several tens of thousands of degrees Kelvin. Similar temperature increases have been detected across the chromosphere of other stars (Wright, p. 124). This layer of solar atmosphere can be viewed as an electric double layer between the plasmas of the solar photosphere and the corona.
"Colour sphere" or layer of the Sun's atmosphere between the photosphere and the corona. Appears as a red ring around the solar limb during a solar eclipse. Plage regions are visible in the chromosphere, usually overlying sunspot groups. EUV radiation is produced in plage.
This middle layer of the Sun's atmosphere has a complicated temperature structure which ranges from 4000 K ( Kelvin ) to about 6500 K. Before this century, observations of the chromosphere were possible only during a total solar eclipse, when the chromosphere could be seen as a thin red ring circling the outer edge of the Moon at mid-eclipse. Today the chromosphere may be observed daily with special Hydrogen alpha (H-alpha) filters and with special devices (coronagraphs) which blot out the bright photosphere of the Sun.
The layer of the solar atmosphere above the photosphere and beneath the transition region and the corona. It is seen during eclipses as a bright red ring around the Sun, and the term burning prairie has been used to describe it.
The layer of the solar atmosphere that is located above the photosphere and beneath the transition region and the corona. The chromosphere is hotter than the photosphere but not as hot as the corona. more
The layer of the solar atmosphere immediately above the visible surface of the sun with flame-like structures called "spicules." The chromosphere extends a few thousand kilometers above the sun’s surface. (TOP OF THE PAGE) (CLOSE WINDOW)
Layer of the solar atmosphere about 14,000 km (8000 naut. ml.) thick, which surrounds the Sun's visible surface (photosphere). It is best observable during an eclipse or other occultation of the solar disc.
Literally meaning "sphere of color," the chromosphere is an outer layer of the solar atmosphere sandwiched between the photosphere and the corona. Prominent features of the chromosphere include spicules, bright hydrogen alpha emission lines, and calcium H and K emission lines. The emission lines suggest that the chromosphere is thousands of degrees hotter than the photosphere.

Prominent features of the chromosphere include spicules, and bright hydrogen alpha emission lines, and calcium H and K emission lines. These emission lines suggest a temperature for the chromosphere higher than the photosphere.
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 when its emission spectrum may be studied.
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). The chromosphere is more visually transparent than the photosphere. The name comes from the fact that it has a reddish color, as the visual spectrum of the chromosphere is dominated by the deep red H-alpha spectral line of hydrogen.
