WEBWhat are the different types, or classes, of flares? Scientists classify solar flares according to their X-ray brightness, in the wavelength range 1 to 8 Angstroms. Flares classes have names: A, B, C, M, and X, with A being the tiniest and X being the largest.
Solar flares: What are they and how do they affect Earth?
WEBJul 6, 2022 · There are five different types of solar flares. Discover what solar flares are, what causes them and the effects they have on Earth in our solar flare guide.
Solar flare - Wikipedia
WEBA solar flare is a relatively intense, localized emission 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 eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.

WEBAug 9, 2011 · Flares happen when the powerful magnetic fields in and around the sun reconnect. They're usually associated with active regions, often seen as sun spots, where the magnetic fields are strongest. Flares are classified according to their strength. The smallest ones are B-class, followed by C, M and X, the largest.
