Sunspot region 4114 has unleashed its most powerful solar flare yet — an X1.9 class that erupted late June 19, triggering ...

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also ...

Sunspot region 4114 has fired off its strongest blast yet — an X1.2-class solar flare that erupted on June 17, triggering ...

A powerful burst of energy on New Year's Eve created the largest solar flare that has been detected since 2017, but scientists say not to be alarmed.

The solar flare was categorized as an X1.08-class flare, making it one of the most powerful classes of flare to be ejected from the sun.

Solar flares are giant explosions that occur in a localized regions of the sun's atmosphere, typically originating from sunspots.

NOAA warns X-class solar flare could hit today, with smaller storms during the week. Here's what to know.

A hyperactive sunspot recently unleashed its third X-class flare in under 24 hours. The X6 flare is the most powerful since 2017 and could be followed by equally massive explosions.

First X-class solar flares of 2013 Date: May 14, 2013 Source: NASA Summary: On May 13, 2013, the sun emitted an X2.8-class flare, peaking at 12:05 p.m. EDT. This is the the strongest X-class flare ...

X-class flares can be 10 times the size of Earth, according to NASA. "The biggest X-class flares are by far the largest explosions in the solar system and are awesome to watch," NASA says.

Solar flares can be classified according to their intensity. X-class flares are the most powerful and least common, while the weakest are categorized as A-class.
