About a week ago, on May 7, 2021, sunspot AR2822 exploded, producing an M3.9-class solar flare, one of the strongest flares of young Solar Cycle 25. The solar storm caused a widespread radio blackout, especially over North America. But are we ready to face a more powerful solar storm right now?

One hundred years ago, on the fifteenth of May 1921, random telegraph and telephone offices in the United States and around the world suddenly burst into flames. Fuses were blown, equipment damaged, connections severed. Undersea telegraph cable service was interrupted. Aurora—as in “the northern lights”—appeared in Pasadena, California. The night sky in Boston was so bright you could read a newspaper.

A railroad office and switching system in New York were also destroyed. The event came to be known as the “New York Railroad Solar Storm of 1921.”

Earth had been slapped, and hard, by the sun. Three successive coronal mass ejections, or CMEs, had first weakened and then penetrated the planet’s natural defenses.
