http://flarecast.eu/spaceweather-solarflare-forecasting Webb6 mars 2015 · Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. We typically see a solar flare by the photons (or light) it releases, at most every wavelength of the spectrum. The primary ways we monitor flares are in x-rays and optical light.

Webb7 mars 2024 · A Solar flare is a powerful burst of electromagnetic radiation in the sun's atmosphere. Flares occur in active areas and are often, but not always, associated with coronal mass ejections, solar particle events, and other solar phenomena.
