- Sunspot - Wikipedia
Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area They are one of the most recognizable Solar phenomena and despite the fact that they are mostly visible in the solar photosphere they usually affect the entire solar atmosphere

On this page you'll find an overview of all the visible sunspot regions on the Sun together with their properties, images and the chances on solar flares or proton events This page is updated daily and the sunspot images every hour Magn Class Magn

What are sunspots and solar flares? Sunspots are areas that appear dark on the surface of the Sun They appear dark because they are cooler than other parts of the Sun’s surface Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots
- Sunspots: What are they, and why do they occur? | Space
Sunspots are dark, planet-size regions of strong magnetic fields on the surface of the sun They can spawn eruptive disturbances such as solar flares and coronal mass ejections (CMEs)
- Sunspots - NASA Science
Sunspots are the visible component of active regions, areas of intense and complex magnetic fields on the Sun that are the source of solar eruptions Sunspots can be seen on the Sun’s photosphere, or visible surface of the Sun

NOTICE: There is an image outage of the Sunspot images due to a cooling water line burst in the Joint Science Operations Center (JSOC) at Stanford University on 2024-11-26 The images are provided by the Solar Dynamics Observatory (SDO) mission Status updates are provided at SDO's JSOC Emergency Resources page
- Sunspots Solar Cycle - NOAA NWS Space Weather Prediction Center
Sunspots are dark areas that become apparent at the Sun’s photosphere as a result of intense magnetic flux pushing up from further within the solar interior Areas along this magnetic flux in the upper photosphere and chromosphere heat up, and usually become visible as faculae and plage – often times termed active regions
