Huge Sunspot Region Facing Earth Develops Beta Gamma Magnetic Field
The sunspot, named AR3068, was first noticed rotating into view over the sun’s eastern horizon a few days ago and has grown since then. Sunspots are regions in the sun’s atmosphere that aren’t quite as hot as the surrounding areas because of intense magnetic fields that prevent heat from rising up below the surface. Since sunspots are relatively cool, they also appear dark. Due to the intense magnetic fields associated with sunspots, they are known to be sources of solar flares and other eruptions of material known as coronal mass ejections (CMEs)....
