NOAA Confirms Solar Storm with Kp 4 Alert
Geomagnetic activity is expected to reach a Kp 4 level midweek, enabling the aurora borealis to be seen across northern U.S. states. This event marks the start of the Northern Lights season for many.
Where and When to See the Northern Lights
The aurora will likely be visible from the Pacific coast all the way to New England. If you have never witnessed the night sky illuminated by green, pink, and purple waves, this upcoming event offers a great chance to experience it.
Scientific Explanation of Aurora Borealis
The glowing lights often associated with Norwegian mythology are actually a result of physics. The sun continuously emits charged particles known as solar wind. Earth's magnetic field acts as a shield, deflecting most of these dangerous particles.
According to NOAA, "The Earth has an 'invisible shield' — the magnetic field — which protects us by deflecting most solar particles."
However, when solar wind intensifies due to eruptions or coronal holes, the charged particles forcefully hit Earth's magnetic shield. Some particles slip through near the North and South poles, colliding with atmospheric gases like oxygen and nitrogen at high speeds, creating the aurora.
Summary
The upcoming minor solar storm will brighten northern U.S. skies with auroras, a stunning natural display caused by charged solar particles interacting with Earth's atmosphere through magnetic polar regions.
"The particles penetrate and collide at high speed with the gases present in our atmosphere—mainly oxygen and nitrogen."
Author's summary: A minor solar storm is set to produce visible Northern Lights across northern U.S. states, showcasing a striking natural phenomenon rooted in Earth's magnetic shield and solar wind forces.
