Another in a series of unusually strong solar storms hitting Earth produced stunning skies full of pinks, purples, greens and blues farther south than normal, including into parts of Germany, the United Kingdom, New England and New York City.
“It was a pretty extensive display yet again,” said Shawn Dahl, a space weather forecaster at the U.S. National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. He said the center has gotten reports of northern lights sightings as far south as New Mexico. “It’s been a wonderful year.”

Such a storm increases the chance of auroras — also known as northern lights — and can temporarily disrupt power and radio signals.
NOAA’s Friday forecast shows continued higher-than-normal activity, but the chances for another overnight show are slim farther south of Canada and the northern Plains states.

But sometimes that solar wind becomes a storm. The sun’s outer atmosphere occasionally “burps” out huge bursts of energy called coronal mass ejections. They produce solar storms, also known as geomagnetic storms, according to NOAA.

Dahl said this storm generated a particularly vibrant display when it hit because the orientation of the storm’s magnetism lined up well with the Earth’s. “We stayed well connected,” he said.
Article continues after this advertisement Why have there been so many solar storms lately?Solar activity increases and decreases in a cycle that last about 11 years, astronomers say. The sun appears to be near the peak of that cycle, known as a solar maximum.
In May, the sun shot out its biggest flare in almost two decades. That came days after severe solar storms pummeled Earth and triggered auroras in unaccustomed places across the Northern Hemisphere.
There will likely be more to come. Dahl said we remain “in the grip” of the solar maximum and it isn’t likely to start to fade until early 2026.
“We’re in for more of the experiences we had last night,” he said.
How can you best see the northern lights?NOAA advises those who hope to see the northern lights to get away from city lights.

The best viewing time is usually within an hour or two before or after midnightsabong online betting, and the agency says the best occasions are around the spring and fall equinoxes due to the way the solar wind interacts with Earth’s magnetic field.
