A solar flare is caused when intense burst of radiation comes from the release of magnetic energy associated with sunspots. Flares are the solar system’s largest explosive events. A CME happens when the outer solar magnetic fields are closed, often above sunspot groups, and the confined solar atmosphere can suddenly and violently release bubbles of gas and magnetic fields.
Large bursts of solar radiation are potentially incredibly dangerous… if you happened to be any closer to the Sun. But thanks to the distance and the Earth’s atmosphere, humans are completely unaffected with the only side effects being.
