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 ...

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 ...
