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

In May 2024, the largest solar flare since 2017 was detected, ranking at an X-8.7 magnitude. Then in 2025, a flare May 13 was classified as an X-1.2, and another the next day was listed as an X-2. ...

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.

A high-powered solar flare erupted from the sun last week, causing a major radio blackout in Europe and Asia. The eruption happened at 3:25 a.m., meaning that the sun wasn't in the Texas sky at ...

A blazing X2.7-class solar flare erupted from sunspot AR4087 early Tuesday, hurling a scorching wave of plasma and charged particles straight at Earth. NASA/SDO.

The sun has had an active few days, firing several powerful solar flares and (plumes of searing-hot solar material out into space. On Tuesday (May 13), a sunspot on the sun's surface named AR4086 ...

This X1.1-class solar flare, which was released from a sunspot named AR4046, marks the first X-class flare the sun has released since early February. "A strong solar flare (R3) occurred and peaked ...

Solar flares are classified based on their strength and fall into five designated categories: A, B, C, M and X. An X-class solar flare is the most intense type of solar flare and can produce as muc… ...

The sun may be 93 million miles away, but that does not stop its solar activity from affecting the Earth's atmosphere, a new study from Queen's University Belfast as found.

To arrive at this finding, the team studied a powerful X5.4 solar flare from March 2012, which was spawned by a large, superactive cluster of sunspots on the sun's surface.

The sun has had an active few days, firing several powerful solar flares and (plumes of searing-hot solar material out into space. On Tuesday (May 13), a sunspot on the sun's surface named AR4086 ...
