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 layer of the Sun above the photosphere where the temperature begins to rise with height
The part of the Sun just above the photosphere. Thousands of miles thick, it is mostly hydrogen gas. It looks like a red ring during an eclipse. The corona is just above the chromosphere.
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.
layer in Solar atmosphere above the photosphere.
"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.
narrow pinkish portion of the Sun's atmosphere lying immediately above the photosphere and below the corona.
Middle solar atmosphere layer defined to begin at the temperature minimum in the solar atmosphere of 4300 degrees Kelvin, extends approximately 3000 km; region where solar flares are observed.
the hot, thin layer of the Sun's atmosphere right above its photosphere.
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
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.
a layer in the Sun and many other starts just above the photosphere
lower layer of Sun's atmosphere directly 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.
A reddish layer in the Sun's atmosphere, the transition between the photosphere and the corona.
The layer between the photosphere and the corona in the atmosphere of the Sun, or any other star, mainly composed of excited hydrogen atoms.
Solar atmosphere extending from the Sun's circumference outwards
The part of the Sun's atmosphere just above the surface.
lower level of the sun's atmosphere.
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 inner layer in the Sun's atmosphere between the photosphere and the corona. The chromosphere is visible during a total solar eclipse.
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.
A line layer of gas just above the photosphere of the sun, it is often marked by solar eruptions called solar flares and prominence.
from the Greek chromos, color. The layer just above the photosphere (see below); it is seen during a solar eclipse, and appears as spikes of light that are a pinkish color.
The part of the Sun's (or another star's) atmosphere between the photosphere and the corona.
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.
The lower atmosphere of the Sun that appears as a thin rosy ring around the edge of the solar disk during a total eclipse.
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, 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 lower level of the solar atmosphere between the photosphere and the corona.
The lower atmosphere of the Sun, between the solar photosphere and corona.
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 part of the sun's atmosphere lying above the bright photosphere, but below the corona.
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.
