Historic Solar and Geomagnetic Storms Hit Earth
A very strong solar storm, the strongest in over 20 years, is happening right now.
This storm can affect satellites and airplanes, especially those flying near the poles.
It might also cause beautiful northern lights to be seen in places like Florida.
Scientists are watching it closely to make sure everything stays safe.
They say it's a historic event because we haven't seen anything this strong since 2003.
The storm can cause some problems with electricity and GPS, but experts think they can handle it.
If you have clear skies, you might want to look up and see the amazing lights in the sky!
An S4-level severe solar radiation storm and G4-level geomagnetic storm are currently impacting Earth, the most intense since 2003.
The storms can affect satellite operations, space missions, and aviation at high latitudes.
Severe geomagnetic storm conditions were recorded following the arrival of a coronal mass ejection (CME) shock.
The storms could lead to widespread aurora visibility, potentially as far south as Florida.
NOAA has advised infrastructure operators and satellite controllers to take precautionary measures and the public to watch for auroras.
