TL;DR Summary

A powerful geomagnetic storm caused the Northern Lights to be visible in places like North Carolina and Arizona on Thursday night. The storm was rated a Level 4 on a five-tier scale by the Space Weather Prediction Center at the National Oceanic and Atmospheric Administration. The colors seen in the sky are dictated by where in the atmosphere the oxygen and nitrogen hit. Typically, anywhere from 50 to 100 storms of this magnitude may occur over an 11-year solar cycle, and they become more likely as the end of the cycle nears in 2025.
