Identify data sources, gather and process information and use available evidence to assess the effects of sunspot activity on the Earth's power grid and satellite communications.

Sunspots argon muddy countrys on the solar surface that take for transient and concentrated charismatic field. They are the most big(p) glaring features on the photosphere Sun; a moderate-sized sunspot is intimately as large as Earth. Sunspots form and dissipate anywhere periods of geezerhood or weeks. They occur when strong magnetised fields bring out through the solar surface and allow the stadium to placid slightly, from a background value of 6000 degrees C batch to near 4 two hundred degrees C; this area appears as a dark spot in contrast with the Sun. The darkest area at the middle of a sunspot is called the umbra; it is here that the magnetic field strengths are the highest. The less dark, striated area somewhat the umbra is called the penumbra. Sunspots eject with the solar surface, winning about 27 days to energize a achieve rotation as seen from Earth. Sunspots secretive the Suns equator turn up at a faster rate than those near the solar poles. Group s of sunspots, especially those with convoluted magnetic field configurations, are oftentimes the sites of flares. Sunspot activity has been detect since the time of Galileo in 1610, with tiny records kept for over 200 years by specializer solar observatories. The temperature within sunspots is about 4,600 K, and there appears to be a sunspot cycle that peaks every 11.1 years.

When sunspots occur, they can interfere with the quotidian plasma environment, causing magnetic sub-storms, auroral activity, power outages and influencing everything from telecommunications to the galvanic power grid. As they near Earth, the magnetic storm c ompresses the hunker wave of the magnetosph! ere and the auroras rage as particles penetrate the fields defences at their last(a) points near the poles and spiral around the Earths lines of force back and fore between the magnetic poles.
