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

X-class flares also have the potential to create global transmission problems and world-wide blackouts, NASA says. New Year's Eve solar flare is strongest in 6 years Fortunately, Sunday's solar ...

NASA's Solar Dynamics Observatory captured sunspot AR3386 blast a long-duration X1.6-class solar flare and X1 flare. See time ...

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 ranked from A-class, which are essentially "background levels," to X, which are the strongest flares, with the rankings of B, C and M in between.

Within each class is a number scale, 1 to 9, to determine its exact impact. But X-class flares can go higher than 9, as in 2003, when a flare was so strong that it overloaded measuring sensors ...

A massive, hyperactive sunspot has just unleashed its third X-class solar flare — the most powerful type of solar explosion — in less than 24 hours. The latest flare, which is the largest of ...

Image of the sun releasing the X-class flare from sunspot AR3354, at the top-right of the image. The flare caused radio blackouts across the western U.S. and the Pacific Ocean NASA Solar Dynamics ...

There is a chance of powerful X-class solar flares that are capable of causing radio blackouts over the next three days, according to forecasters. The National Oceanic and Atmospheric ...

Explore the impact of a near X-class solar flare, registering M9.5, as it disrupts radio signals across the Pacific. The eruption was sunspot AR3654's most powerful yet.
