Areas that are relatively dark compared to their surroundings. Areas that are relatively cooler compared to the surrounding area. The umbra (very dark region) is about 3800˚k. The penumbra (not so dark region) is about 3900˚k. The Penmbra has a radial filamentary structure. Zeaman Effect – Process by which the splitting of magnetic fields is made known. Caused by the Differential Rotation . Magnetic field – Pairs 1 north, and 1 south (corona above hotter) The Chromosphere – lies just above the photosphere. It appears red because of the strength of the α (hydrogen) Balmer emission lines....
