Solar flares are ranked on a scale from A to X, Space.com reports, with X-class flares being the most powerful and each rank up represents a tenfold increase in strength.

Solar flares measured around X1 — like the May 13 and 14 events — indicate strong flare intensity. An X10 flare is described as as a severe event, according to NOAA.

Recent solar flares in 2022. The strength and frequency of flares, along with many other aspects of solar activity, varies in a "solar cycle" that lasts roughly 11 years.

But solar activity may not be the only reason the number of supercharged solar explosions skyrocketed last year, experts told Live Science. There were a total of 54 X-class flares in 2024 ...

Solar flares are classified based on their strength, much like earthquakes, according to NASA.The scale ranges from B-class on the lowest end to C-class, then M-class, and finally, X-class.
