What's pinkish-red and invisible? A spectroscopic measure of chromospheric activity on other stars is the Mount Wilson S-index.

At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission). See also Superflare#Spectroscopic observations of superflare stars. In particular, one of its strongest lines is the Hα at a wavelength of 656.3 nm; this line is emitted by a hydrogen atom whenever its electron makes a transition from the n=3 to the n=2 energy level. The chromosphere undergoes a phenomenon called solar flares wherein a sudden and intense brightening rises in a couple of minutes and fades away in half an hour to several hours. Consequently, the chromosphere is ordinarily difficult to see because there's so little material in it, resulting in transparency at most visible wavelengths. The chromosphere is the second outermost most layer of the sun’s atmosphere, which is only visible to the naked eye during a solar eclipse. Many interesting phenomena can be observed in the chromosphere, which is very complex and dynamic: See the flash spectrum of the solar chromosphere (Eclipse of March 7, 1970). imaginable degree, area of The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. It is a layer of gas that gets hotter with increasing height, the opposite of the photosphere. You can test out of the The chromosphere is the second outer layer of the sun's atmosphere, extending from 250 miles to 1,300 miles above the surface of the sun. This lesson will explore some of the interesting features of the second layer of the sun's atmosphere, the chromosphere, including spicules and its pinkish hue. Chromosphere literally means “sphere of color.” This is the second of the Sun’s three main layers of atmosphere. In certain wavelengths of light, spicules give the Sun a grassy texture. To cook in water that begins cold and then reaches a boil. Temperatures in the chromosphere range from 4,000 K (6,700 degrees F or 3,700 degrees C) near the surface and rise up to 8,000 K (14,000 degrees F, or 7,700 degrees C) at the top. This layer sits just above the photosphere between about 400 km (250 miles) and 2,100 km (1,300 miles) above the solar surface. Not sure what college you want to attend yet?
