How do sunspots form
Did you know?
WebSunspots are thought to be cooled by the suppression of their strong fields with the convective motions bringing heat from below. For this reason, there appears to be a lower limit on the size of the spots of approximately 500 kilometres. Smaller ones are rapidly heated by radiation from the surroundings and destroyed. Sunspots have two main structures: a central umbra and a surrounding penumbra. The umbra is the darkest region of a sunspot and is where the magnetic field is strongest and approximately vertical, or normal, to the Sun's surface, or photosphere. The umbra may be surrounded completely or only partially by a brighter region known as the penumbra. The penumbra is compo…

The result: an aurora, and a special sight for the astronauts on board the space station. A coronal mass ejection, or CME, burst from the sun on Aug. 15, 2014. When it arrived at Earth, it sparked aurora over North America.
WebSunspot umbrae are the most strongly magnetized regions of the Sun accessible to spectropolarimetric observations. They are cool and dark, characterized by magnetic fields that are close to vertical with respect to the photosphere, and exhibit constrained columnar convective motions that are only poorly understood. port adelaide power scheduleWebJun 4, 2024 · How do sunspots form on the Sun?
