Chromosphere spectrum
Did you know?
WebThe 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 (chromium) color often seen around the rim of the Moon at total solar eclipses. continuum Optical radiation arising from broadband emission from the photosphere. WebThe structure of the solar chromosphere, and in particular of internetwork regions, is still an issue of intensive scientific debate. On the one hand UV diagnostics imply a hot layer with only small temperature fluctuations, as expressed in static semi-empirical 1-D models like, e.g., FAL A, VAL C ([\astroncite Fontenla et al.1993]; [\astroncite Vernazza et al.1981]).

When there is no light it appears as black in the spectrum. Here is a spectrum showing Fraunhofer lines
WebThe chromosphere displays sunspots (cooler regions of the Sun), filaments, prominences, active regions, spicules, solar flares and many unclassified magnetic phenomena. Corona The corona is the outermost layer of our Sun with a temperature around 900,000 degrees F! The Corona is the Sun's outer atmosphere and can be difficult to see.
