What name is given to the silvery aureole enveloping the sun's chromosphere?
Chromosphere the Mount Wilson S-index. See also Superflare#Spectroscopic observations of superflare stars. Chromosphere The chromosphere (literally, "sphere of color") is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilometers deep. The chromosphere's rosy red color is only apparent during eclipses. The chromosphere sits just above the photosphere and below the solar transition region. The layer of the chromosphere atop the photosphere is homogeneous. A forest of hairy-appearing spicules rise from the homogeneous layer, some of which extend 10,000 km into the corona above. The density of the chromosphere is only 10 times
Chromosphere of the atmosphere of Earth at sea level. This makes the chromosphere normally invisible and it can be seen only during a total eclipse, where its reddish color is revealed. The color hues are anywhere between pink and red. Without special equipment, the chromosphere cannot normally be seen due to the overwhelming brightness of the photosphere beneath. The density of the chromosphere decreases with distance from the center of the Sun. This decreases logarithmically from 10 particles per cubic centimeter, or approximately to under at the outer boundary. The temperature decreases from the inner boundary at about 6,000 K to
