Solar flare - Wikipedia
A 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.
What 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. Each category has nine subdivisions ranging from, e.g., …

The Classification of X-ray Solar Flares - Space weather
M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth.

M-class solar flares are what we call the medium large solar flares. They cause small (R1) to moderate (R2) radio blackouts on the daylight side of the Earth. Some eruptive M-class solar flares can also cause solar radiation storms.
Solar flares: What are they and how do they affect Earth?
Jul 6, 2022 · According to NASA, X-class flares are the most powerful solar flares. Then there are M-class flares that are 10 times smaller than X-class flares, then C-class, B-class and...

X-class flares are the biggest; they are major events that can trigger radio blackouts around the whole world and long-lasting radiation storms in the upper atmosphere. M-class flares are medium-sized; they generally cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare.
