How much energy does a solar flare release

Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona. The same energy releases may also produce coronal mass ejections (CMEs), although the relationship between CMEs and flares is not well understood.

How Big Can Solar Flares Get And How Far Do They Travel?

Solar flares are localized bursts of radiation produced when energy trapped by twisted magnetic fields gets released suddenly. This accelerates charged particles from the Sun''s plasma.

Radiation From Solar Activity | US EPA

Solar flares are large eruptions of energy coming off the Sun containing several different forms of energy: heat, magnetic energy, and ionizing radiation. The ionizing radiation released during solar flares includes x-rays and gamma rays. These rays of ionizing radiation can damage satellites because they are in space and are not protected by
