About the Northern Lights

The Northern Lights, or Aurora Borealis, are a natural light display in Earth's sky, predominantly seen in high-latitude regions. They occur when charged particles from the Sun collide with atoms in Earth's atmosphere, causing them to emit light. The colors vary based on the type of gas particles involved—oxygen produces green and red, while nitrogen creates blue and purple hues.

The Kp index measures geomagnetic activity on a scale from 0 to 9. A Kp index of 0-2 indicates quiet conditions, 3-4 suggests minor to moderate activity, 5-6 means active conditions with visible aurora at mid-latitudes, and 7-9 indicates severe geomagnetic storms with aurora potentially visible at lower latitudes.
