WebSunspots can be up to 12 times larger than Earth. Sunspots are surface disturbances caused by magnetic storms. Sunspots can produce flares and prominences. Sunspots are brighter than the rest of the Sun's surface. On its way to Earth, solar winds first encounter the magnetosphere. The dominant wavelength emitted by Earth is infrared. Sunspot numbers over the past 11,400 years have been reconstructed using carbon-14 isotope ratios. The level of solar activity beginning in the 1940s is exceptional – the last period of similar magnitude occurred around 9,000 years ago (during the warm Boreal period).
