“This is likely one of the largest solar radio events ever recorded,” NOAA wrote Thursday in a report regarding the flare, which is caused by localized explosions on the sun’s surface that expel intense bursts of electromagnetic radiation.
The alarming solar event occurred Thursday after an active sunspot named AR 3514 erupted with a large class X.28 solar flare — the most powerful variety that the sun is capable of producing, as seen in ominous photos captured by NASA’s Solar Dynamics Observatory.
