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]).

Its name comes from the Greek root chroma (meaning color), for it appears bright red when viewed during a solar eclipse. The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun. eagle bank cinti
