Sunspots: sunspots are cooler and darker regions of the Sun's photosphere created by magnetic fields piercing that region of the Sun's visible surface.
(2) Plages: plages are bright regions in the chromosphere associated with magnetic fields in the process of emerging from the Sun.
(3) Flares: flares are ejections of large volumes of gas. These gases sometimes head our way, causing auroras and radio interference. A flare is a much less massive ejection than a coronal mass ejection
(4) Filaments, and (5) Prominences: filaments and prominences are the same feature seen from different angles. They are loops of magnetic fields carrying gases aloft.
(6) Coronal holes: coronal holes are dark, and therefore cooler, portions of the corona that appear over sunspots. They are called 'holes' because these cooler areas of the corona act as conduits for gases to flow out of the sun.
(7) Coronal mass ejections: coronal mass ejections and flares are ejections of large volumes of gas. These gases sometimes head our way, causing auroras and radio interference.
For all of the features of the active sun listed and described above, magnetic fields play important roles in determining the activity of the active sun.
