Sun's 'Magnetic Island' Creates Strong Geomagnetic Storm
The sun can sometimes send out strong bursts.
Recently, a hidden magnetic area on the sun caused a bigger solar event than expected, called a G3 geomagnetic storm.
This created a beautiful light show called the Northern Lights.
This time, the lights were visible across the US, even in places like Texas!
It serves as a reminder that small things on the sun can have big effects on Earth.
Researchers are studying these events to better predict and prepare for them.
A G3 geomagnetic storm occurred on September 14-15.
The storm was caused by a hidden magnetic 'island' on the Sun.
The storm created auroras visible across the United States.
Forecasters initially predicted a weaker storm.
Residents in Texas reported sightings of the Northern Lights.
