What are the different types, or classes, of flares? - Stanford …
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., …
Solar flare - Wikipedia
The modern classification system for solar flares uses the letters A, B, C, M, or X, according to the peak flux in watts per square metre (W/m 2) of soft X-rays with wavelengths 0.1 to 0.8 nanometres (1 to 8 ångströms), as measured by GOES satellites in geosynchronous orbit.
The Classification of X-ray Solar Flares - Space weather
Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth. This figure shows a series of solar flares detected by NOAA satellites in July 2000: Each category for x-ray flares has nine subdivisions ranging from, e.g., C1 to C9, M1 to M9, and X1 to X9. It's a logartithmic scale.

What are solar flares? What is a Coronal Mass Ejection (CME)? The plot on this page shows us the most recent 24-hour solar X-ray data from the primary GOES satellite.
Solar flares: What are they and how do they affect Earth?
Jul 6, 2022 · Solar flares are large explosions from the surface of the sun that emit intense bursts of electromagnetic radiation. The intensity of the explosion determines what classification the flare...

C-class solar flares are minor solar flares that have little to no effect on Earth. Only C-class solar flares which are long in duration might produce a coronal mass ejection but they are usually slow, weak and rarely cause a significant geomagnetic disturbance here on Earth.
Solar Flares (Radio Blackouts) - NOAA / NWS Space Weather …
SWPC currently forecasts the probability of C, M, and X-class flares and relates it to the probability of an R1-R2, and R3 or greater events as part of our 3-day forecast and forecast discussion products. SWPC also issues an alert when an M5 (R2) flare occurs.
ESA - What are solar flares? - European Space Agency
Minor radiation storms sometimes follow an M-class flare. C-class flares are small with few noticeable consequences here on Earth. At its peak, a C-class flare is ten times less powerful than an M-class flare. B-class flares are ten times smaller or weaker than C-class flares.
Solar Flares FAQs – Solar Cycle 25 - NASA Blogs
Jun 10, 2022 · Solar flares only affect Earth when they occur on the side of the Sun facing Earth. Solar flares are rated into different classes based on their strength, or energy output, and the effect a flare will have on Earth depends on what class it is (B, C, M, and X classes, with X being the most intense).

Flares are characterized by their brightness in X-rays (X-Ray flux). The biggest flares are X-Class flares. M-Class flares have a tenth the energy and C-Class flares have a tenth of the X-ray flux seen in M-Class flares.
