A powerful solar storm put on a spectacular light show around the world overnight, but caused seemingly minor disruptions to power grids, communications and satellite positioning systems. The U.S. National Oceanic and Atmospheric Administration said extreme geomagnetic storms continued into Saturday, with preliminary reports of power outages, high-frequency communications and global positioning system outages.

But the Federal Emergency Management Agency said no FEMA sites had reported serious impacts from the storms as of noon Saturday morning. NOAA predicts strong flares will continue through at least Sunday, and a spokesperson said in an email that the agency’s Space Weather Prediction Center is well prepared for the storm.

On Saturday morning, SpaceX’s Starlink satellite internet service said on its website that the service was down and that its team was investigating. CEO Elon Musk wrote on X tonight that their satellite “is under a lot of pressure but has held up so far.”

The vibrant purple, green, yellow and pink hues of the northern lights have been reported to be seen around the world in Germany, Switzerland, China, England, Spain and other countries.

In the US, Friday’s solar storm pushed the lights further south than usual. The National Weather Service office in Miami confirmed sightings in the Fort Lauderdale and Fort Myers areas of Florida. Meteorologist Nick Carr said another forecaster who lives near Fort Lauderdale photographed the lights and was familiar with them because he used to live in Alaska.

People in Kansas, Nebraska, Iowa, Michigan, Minnesota and other Midwestern states were able to take photos of the bright colors on the horizon.

NOAA said the solar storm will continue through the weekend, offering many people a chance to see the Northern Lights on Saturday night. The agency warned of a rare severe geomagnetic storm when a solar flare reached Earth on Friday afternoon, hours earlier than expected. NOAA warned FEMA, as well as power plants and orbiting spacecraft operators, to take precautions.

“Most people on planet Earth won’t have to do anything,” said Rob Steenburgh, a scientist with NOAA’s Space Weather Prediction Center.

“This is truly a gift of space weather: the aurora borealis,” Steenburg said. He and his colleagues say the best images of the auroras come from phone cameras, which capture the light better than the naked eye.

Take a photo of the sky and “that might be a little treat,” said Mike Bettwee, the forecast center’s operations manager. In 1859, the most powerful solar storm in recorded history caused auroras in Central America and possibly even Hawaii.

NOAA space forecaster Sean Dahl told reporters that this storm poses a threat to high-voltage power lines, not the power lines usually found in people’s homes. Satellites may also be affected, disrupting navigation and communications services on Earth.

For example, in 2003, a severe geomagnetic storm caused power outages in Sweden and damaged power transformers in South Africa. Even when the storm is over, signals between GPS satellites and ground receivers may be jammed or lost, according to NOAA. But there are so many navigation satellites that any outages shouldn’t last long, Steenburgh said.

Since Wednesday, the sun has caused intense solar flares that have resulted in at least seven plasma explosions. Known as a coronal mass ejection, each explosion can contain billions of tons of plasma and the magnetic field of the Sun’s outer atmosphere, or corona. NOAA said the outbursts were associated with a sunspot whose diameter is 16 times the diameter of the Earth. It’s all part of increasing solar activity as the Sun approaches the peak of its 11-year cycle.
