An astrophotographer has captured an extremely rare and "difficult" photo of a solar flare exploding from the sun at the ...

Solar flares, through their intense bursts of X-ray radiation, ... Reflection height (H′): An effective altitude from which VLF waves are reflected in the ionosphere, ...

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.

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

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 solar flare on New Year's Eve, rated as an X-5, was the largest detected since the 2017 eclipse, when a X8.2 flare X8.2 flare occurred, according to NOAA.

"Solar activity has been at high levels with ten M-Class flares and one X-Class flare. An impulsive X2.3/2b occurred at 06/1324 UTC originating from Region 3883," NOAA's Space Weather Prediction ...

At 12:02 p.m. Eastern time on Thursday, a massive X-class solar flare — the strongest kind — launched off the sun. It was the most intense of the sun’s current 11-year cycle, and the most ...

On Tuesday, the sun launched its largest solar flare in seven years and the largest of the ongoing 11-year solar cycle. It marks the culmination of an excessively busy period for our closest star.

Solar flares are closely related to another solar phenomenon called a coronal mass ejection, or CME. Where there's a flare, there's likely to be a CME, just like where there's smoke there's fire.

Solar flares are measured on a scale of A, B, C, M and X, with each class being 10 times more powerful than the previous. The most powerful solar flare of this solar cycle—of which we are ...

Waves of solar flares keep pouring out of the sun, sparking "rolling" radio blackouts across the world. Active sunspot regions on the sun's surface are responsible for the flares, which are ...
