They're usually associated with active regions, often seen as sun spots, where the … WebThe classification of solar flares. Solar flares are classified as A, B, C, M or X according to the peak flux (in watts per square metre, W/m 2) of 1 to 8 Ångströms X-rays near …
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 ) of soft X-rays with wavelengths 0.1 to 0.8 nanometres (1 to 8 ångströms), as measured by the GOES spacecraft in geosynchronous orbit. The strength of an event within a class is noted by a numerical suffix ranging from 1 up to, but excluding, 10, which is also the factor for that event within the class. Hence, an X2 flare is twice … WebJul 10, 2024 · GOES15 1-8 Å solar X-ray flux from 2011-02-14 to 2011-02-15. The GOES flare classification is provided on the minor y-axis.
