sunspots
Dark stellar patches
Sunspots are dark patches on the sun's surface, cooler regions that appear in cycles and can affect radio communications and weather on Earth.
The term sometimes describes the bright spots or floaters people see in their vision after looking at intense light, though this usage is technically imprecise.
