Solar Patch is a term used to describe a SUNSPOT, which is an area of the Sun's surface that appears darker than its surroundings due to its lower temperature. Sunspots are caused by intense magnetic activity and can last anywhere from a few hours to several months. They are associated with solar flares, which are powerful bursts of radiation that can cause disruptions in communication systems on Earth. Solar patches are also known to affect the Earth's climate, as they can reduce the amount of sunlight reaching the planet.
