Magical Photos Show Northern Lights After Huge Halloween Solar Storm

The Northern Lights put on a spectacular show over the Halloween weekend amid a period of heightened solar activity—and social media users have captured some of the magic on camera.

The auroras could be seen from the U.K. to North America.

In Iceland particularly, they were so bright that people were able to capture clear shots on mobile phone cameras.

Twitter user Paul Black, who managed to capture the lights on his iPhone, wrote: "Sorry, I know you are all Halloweening but I'm truly shaking in my boots at just seeing the Northern Lights in Iceland and I must share."

The dancing lights were also captured over Iceland via phone cameras by an amateur photographer who described the phenomenon on Twitter as "absolutely incredible".

Sorry I know u r all halloweening but I’m truly shaking in my boots at just seeing the northern lights in Iceland and I must share x god bless iPhone 12 Pro lapse cameras x

#NorthernLights are absolutely incredible tonight! They’re even visible from downtown #Reykjavik

This was taken on my #iPhone on our way back to the hotel 😳

The auroras were also seen over the U.K. The photo below, captured by astronomer Daniel Monk, shows them shining in green and red over Dunstanburgh Castle in Northumberland.

Monk, also an astrophotographer, told Newsweek that the weekend's space weather "sparked a bigger than usual aurora."

He added: "It wasn't a colossal display and nowhere near as good as it can be, but it was decent."

In Scotland, someone managed to glimpse the lights appearing just below The Plough constellation.

And in Portugal Cove in Newfoundland, Canada, a Twitter user managed to see the lights by setting up a camera with a long exposure setting even though they were not visible to the naked eye at the time.

Good display of Aurora Borealis tonight near Dornoch, Scotland with added bonus of the The Plough constellation in the sky. Love the beams! #Auroraborealis #NorthernLights

The Halloween light show took place after space weather experts issued a warning that the sun would be particularly active over the weekend, directing charged particles towards the Earth that could disrupt electrical systems and radio communication.

The warning was issued by the U.S. National Oceanic and Atmospheric Administration's Space Weather Prediction Center which said a G3 or "Strong" geomagnetic storm was on the way after "a significant solar flare and Coronal Mass Ejection (CME) from the sun" occurred on October 28.

"Impacts to our technology from a G3 storm are generally nominal," the center said.

"However, a G3 storm has the potential to drive the aurora further away from its normal polar residence and if other factors come together, the aurora might be seen over the far Northeast, to the upper Midwest, and over the state of Washington."

The Northern Lights occur when charged particles from the sun interact with Earth's magnetic field.

These charged particles are the result of CMEs which, like solar flares, are an example of increased solar activity.
