Solar Flares

Home > Space Sciences > Space Weather > Solar Flares

A sudden and intense release of energy from the Sun's surface, which can cause radio blackouts and other impacts on Earth's environment.

"A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere."
"Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena."
"The occurrence of solar flares varies with the 11-year solar cycle."
"Solar flares are thought to occur when stored magnetic energy in the Sun's atmosphere accelerates charged particles in the surrounding plasma."
"This results in the emission of electromagnetic radiation across the electromagnetic spectrum."
"High-energy electromagnetic radiation from solar flares is absorbed by the daylight side of Earth's upper atmosphere, in particular the ionosphere, and does not reach the surface."
"This absorption can temporarily increase the ionization of the ionosphere."
"The ionization of the ionosphere may interfere with short-wave radio communication."
"The prediction of solar flares is an active area of research."
"Yes, solar flares occur only on the Sun."
"Flares also occur on other stars, where the term stellar flare applies."
