Active region: Regions, Overview & Region numbers

In solar physics, an active region is a temporary feature in the Sun's atmosphere characterized by a strong and complex magnetic field. Active regions are often associated with sunspots and are commonly the source of violent eruptions such as coronal mass ejections and solar flares. The number and location of active regions on the solar disk at any given…
