aurinkokuvioita

Aurinkokuvioita, also known as sunspots, are temporary phenomena on the photosphere of the Sun that appear as dark spots compared to the bright face of the Sun. They are caused by intense magnetic activity, which inhibits convection by the Sun's heat transport mechanisms to its surface. The magnetic field causes strong heating in the chromosphere above the spot, forming areas of super-hot solar material. Sunspots are temporary features that can last anywhere from a few days to a few months, but typically last about two weeks. They are usually found in pairs or groups, with each spot having opposite magnetic polarity. The largest sunspots can be tens of thousands of kilometers in diameter. Aurinkokuvioita are important for studying the Sun's magnetic field and its influence on space weather. They are also used to track the solar cycle, which is an approximately 11-year cycle of solar activity. The number of sunspots visible on the Sun's surface varies with this cycle, with a maximum number of sunspots occurring around the peak of the cycle.
