Did you look up late last night and see a colorful glow in the sky? It was the Northern Lights!

Tonight there is another chance to see them once the sun goes down.

The sun is causing this space weather with eruptions of plasma and magnetic field structures from the sun's atmosphere. When that arrives at earth it can produce a geomagnetic storm and give us the northern lights.

These storms have intensity scales, last night was a severe G4 and tonight could be another G4.

No life threatening impacts from a space storm but it could disrupt things modern Infrastructure technology or satellites and your GPS for example.

The colors vary based on the type of gas involved and the altitude at which the collisions occur.

Green is the most common and produced by oxygen at lower altitudes. Red is also oxygen but at higher altitudes. Blue and purple are created by nitrogen at lower altitudes.

If you saw the northern lights last night or see them tonight, please send us your pictures or videos.
