- Sunspot - Wikipedia
Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection

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
- 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
- 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) These

- What are Sunspots and What Causes Them? - High Point Scientific
Sunspots often form in groups, with each sunspot usually somewhere between 10,000 and 50,000 miles (16,000 to 80,000 kilometers) in diameter In comparison, the Earth is just under 8,000 miles (13,000 kilometers) in diameter, so the vast majority are larger than the Earth
