Summary[edit]

Description
العربية: التباينُ الشمسي في الفترة الممتدة من 1975 حتى 2005 (30 سنة).
English: 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.
Español: Variaciones en el ciclo solar.
Suomi: Auringon aktiivisuuden syklit aikavälillä 1975–2005.

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Solar-cycle-data.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
