NOAA says ‘extreme’ Solar storm will persist through the weekend
After a night of stunning auroras across much of the United States and Europe on Friday, a severe geomagnetic storm is likely to continue through at least Sunday, forecasters said.
The Space Weather Prediction Center at the US-based National Oceanic and Atmospheric Prediction Center observed that 'Extreme' G5 conditions were ongoing as of Saturday morning due to heightened Solar activity.
"The threat of additional strong flares and CMEs (coronal mass ejections) will remain until the large and magnetically complex sunspot cluster rotates out of view over the next several days," the agency posted in an update on the social media site X on Saturday morning.
For many observers on Friday night the heightened Solar activity was welcomed. Large areas of the United States, Europe, and other locations unaccustomed to displays of the aurora borealis saw vivid lights as energetically charged particles from the Solar storm passed through the Earth's atmosphere. Brilliantly pink skies were observed as far south as Texas. Given the forecast for ongoing Solar activity, another night of extended northern lights is possible again on Saturday.
There were also some harmful effects. According to NOAA, there have been some irregularities in power grid transmissions, and degraded satellite communications and GPS services. Users of SpaceX's Starlink satellite internet constellation have reported slower download speeds. Early on Saturday morning, SpaceX founder Elon Musk said the company's Starlink satellites were "under a lot of pressure, but holding up so far."
