A solar flare hit Earth on Halloween, treating stargazers to an eerie display of the Northern Lights.
As charged particles from the star collided with the planet’s magnetosphere, they created a beautiful and spooky green and orange aurora.
Astronomers, photographers, and delighted amateurs captured dozens of pictures and videos of the show and shared them on social media, including pictures from Northumberland in England.
Andrew Douglas, who often shares pictures of the Farne Island off England’s northeastern coast, took pictures of the Northern Lights as they danced near the horizon.
The flare – officially known as a coronal mass ejection (CME) – left the sun on Thursday and comes as we enter.
Although it was an X1-class flare – the strongest there is – the CME “was much slower and waker than expected” according to the UK’s Met Office.
Michael Charnick, an American meteorologist visiting Iceland, captured a Halloween picture using just his iPhone 13.
There are concerns that some flares could be so powerful they might interrupt electronic systems on the surface of the Earth.
Recently an alert was published by the US National Oceanic and Atmospheric Administration (NOAA) warning the geomagnetic storm could cause power grid fluctuations with voltage alarms at higher latitudes, where the Earth is more exposed.
Thomas Klein, a freelance journalist currently trying to build a wooden cabin in Swedish Lapland, shared several more pictures of the lights appears almost directly overhead.
NOAA added that satellites may be impacted too and could exhibit “orientation irregularities” meaning ground control would have to redirect them, as well as anything in low-Earth orbit experiencing increased drag.
Comedian Paul Black, who recently performed at the Edinburgh Fringe Festival, captured four pictures using an iPhone 12 Pro’s timelapse feature.
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

The geomagnetic storm NOAA issued the warning about was only expected to reach category G2, which is moderately strong according to the agency.
In the end that storm and this X1-class flare did not cause major disruption, but such disruption has been caused in the past.
Tonight was an actual dream. KP7 aurora for our workshop groups first night. So grateful they got to see this incredible show 💚🙏

Space weather experts reference the Carrington Event, believed to be the largest solar storm ever recorded, which hit Earth in 1859.
The Carrington Event left an aurora visible across the sky, even in latitudes much closer to the equator, and was described in contemporary reports as even brighter than the light of a full moon.
It caused the failure of telegraph systems all across Europe and North America, and a similar storm today could cause trillions of dollars in damage globally.
Solar activity has been observed rising and falling naturally every 11 years, although not quite like clockwork, and astronomers believe we are now in the early years of a new busy period.
