Solar particle event - Wikipedia
WEBIn solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a][1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in interplanetary space by a coronal mass ejection shock.

WEBThese powerful eruptions can generate any or all of the following: a bright flash of light called a solar flare. a radiation storm, or flurry of solar particles propelled into space at high speeds. an enormous cloud of solar material, called a coronal mass ejection, that billows away from the Sun.
How NASA Tracked the Most Intense Solar Storm in Decades
WEBDuring the first full week of May, a barrage of large solar flares and coronal mass ejections (CMEs) launched clouds of charged particles and magnetic fields toward Earth, creating the strongest solar storm to reach Earth in two decades — and possibly one of the strongest displays of auroras on record in the past 500 years.
