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.

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.

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.

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.

On April 8, there was just one minor C-class solar flare that ended several hours before totality began anywhere in the U.S., and it did not launch a CME, according to SpaceWeatherLive.com.

What is a solar flare? Solar flares are caused by the Sun’s magnetic fields, which are strongest in the dark areas called sunspots. When inactive, these fields look like loops. However, when the ...
