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.
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. ...
"WOW, happening now: an X2.7 flare from AR 4087 rotating in. This is getting intense, especially as this active region turns closer into view. This same AR just produced an M5.3 flare a few hours ago.
And “Flares of this magnitude are not frequent,” according to a statement from the NOAA officials. A blazing X2.7-class solar flare erupted from sunspot AR4087 early Tuesday, ...
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 ...
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 ...
Sol Versus Ionospheric Propagation This happens more often than you might think. In October, AR2775 set off two C flares and while plasma from the flare didn’t hit Earth, UV radiation caused a ...
Solar flares are caused when magnetic field lines from sunspots – the darker, cooler regions of the sun – tangle up and erupt. Despite being the cooler part of the sun, they can still be ...
For example, an X-class flare is 10 times stronger than an M-class event, and 100 times more powerful than a C-class flare. C-class flares and below are generally too weak to produce any ...
According to an article published in Nature Astronomy, a research lab at the California Institute of Technology (Caltech) managed to create its own solar flare that is small enough to fit inside a ...
A powerful solar flare erupted from the sun on July 29, but while the storm did not unleash a big cloud of particles directed at Earth, it was almost the most powerful type of sun storm, according ...
