La cromosfera (literalmente, "esfera de color") es una capa delgada de la atmósfera del sol por encima de la fotosfera y por debajo de la corona . Diferentes modelos teóricos la sitúan entre 2200 y 5000 km de espesor. es.wikipedia.org/wiki/Cromosfera

The chromosphere (literally, "sphere of color") is the second of the three main layers in the Sun's atmosphere and is roughly 2,000 kilometers deep. It sits just above the photosphere and just below the solar transition region. en.wikipedia.org/wiki/Chromosphere
