X-class is the most powerful type of solar flare, 1 million times stronger than a nuclear bomb.
Sun ejection may hit Earth's magnetic field, causing geomagnetic storms
The solar event may lead to auroras glowing in the night sky.
Arctic Circle hit by radio blackout
A plume of solar protons spat out by the sun has accelerated towards the Earth, and were funneled down into the polar regions by our magnetic field.
Strange light phenomenon nicknamed "STEVE" delights onlookers: "Amazing"
STEVE usually appears during geomagnetic storms but is a different process to the formation of the northern and southern lights
Why the northern lights are visible over U.S.
The northern lights were spotted as far south as California due to a severe G4 geomagnetic storm pummeling Earth's atmosphere and magnetic field.
Stunning images capture northern lights over U.S. and Canada
A severe G4 geomagnetic storm, triggered by a coronal mass ejection from the sun, led to the spectacular aurora borealis being seen across North America.
Red auroras seen as far south as Florida in rare light show
The northern lights appear redder further south, due to observers only being able to see the top of the light show.
Photos show northern lights in rare appearance over North America
The northern lights painted the night sky green across the northern parts of the U.S. and Canada, and were even seen as a faint pink as far south as New Mexico.
Massive plasma tornado seen on surface of the sun
Solar tornadoes can have wind speeds of up to around 310,000 miles per hour, as opposed to the 300 mph top speed of tornadoes on Earth.
The sun is getting fired up—and it's way beyond what experts predicted
Solar Cycle 25 is defying expectations it would be as inactive as the previous cycle, as sunspot numbers are already reaching Solar Cycle 24's maximum levels.
Massive solar storm slamming into Earth sparks aurora around the world
The spectacular red lights in the sky were caused by a G3 geomagnetic storm interacting with Earth's atmosphere.

Sunspot AR3190 is covering around 25 millionths of the solar disk, while the Earth would cover 169 millionths of the sun's surface.
Three massive Earth-facing sunspots have developed "delta" magnetic fields
The sun spat out a rare X1.9 flare on January 9 from one of three large and unstable sunspots.
Earth in direct firing line for X-class solar flare from enormous sunspot
The AR3182 sunspot has developed an unstable "beta-gamma-delta" field, making it more prone to spewing out violent X-class solar flares.
Sun may be waking up with sudden surge in activity and hyperactive sunspot
Five large sunspots have appeared on the Sun's surface, and are facing towards the Earth, putting us in the line of fire for solar flares and CMEs.
"It's alive": Sunspot explodes creating huge solar flare, radio blackouts
Sunspot AR3141 erupted around midnight on November 7, sending high-energy X-rays racing toward Earth.

The explosion far surpassed the Earth in size. "I tracked it nearly a million miles out into space," astrophotographer Andrew McCarthy wrote on Reddit.
Cracks Are Appearing in Earth's Magnetic Field as the Equinox Approaches
The phenomenon could mean that more auroras are visible across the northern hemisphere as the fall equinox approaches this month.
