What “sunspot” means
Wiktionary · Wikipediasunspot/ˈsʌnspɒt/
- nounA region on the sun's surface with a lower temperature than its surroundings and intense magnetic activity.
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. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. Their number varies according to the approximately 11-year solar cycle.
