[edit] Summary

Español: Variaciones en el ciclo solar.

This picture depicts the last three solar cycles as measured in solar irradiance, sunspot numbers, solar flare activity, and 10.7 cm radio flux. Solar irradiance, i.e the direct solar power at the top of the Earth's atmosphere, is depicted as both a daily measurement and a moving annual average. All other data are depicted as the annual average value.

See w:solar variation for more information.
