Sunspot characteristics
WebUltimately, when the sun has lots of sunspots (dark areas) and bright spots (called faculae), solar energy output increases overall. On the other hand, when few sunspots and faculae are present, solar energy output decreases overall. The variation in solar energy during these cycles isn't large, however, only varying by about 0.1 percent. WebOur Sun is always too bright to view with the naked eye, but it is far from unchanging. It experiences cycles of magnetic activity. Areas of strong activity manifest as visible spots—sunspots—on the Sun’s surface. The year 2008, however, earned the designation as the Sun’s “blankest year” of the space age.

WebOct 15, 2024 · Sunspots are created where bits of the Sun's magnetic field poke out from the interior into the Sun's atmosphere. Lasting from days to months, sunspots range in size from 1,000 to 100,000 miles (1,600 to …
WebUneven rotation of the sun distorts and twists magnetic field lines in the interior. The twisted field lines break through the surface forming sunspot pairs. Eventually, the field lines break apart and sunspot activity decreases. The cycle starts again.
