Abstract from DBPedia
    Active regions are temporary regions on the Sun characterized by strong and complex magnetic fields. They are associated with sunspots and are often the source of violent eruptions known as coronal mass ejections and solar flares. The number of active regions at any given time is dependent on the solar cycle. Active regions are typically found in the lower latitudes near the equator.
