What I wouldn't pay or do to see this amazing sight!! Thanks to National Geographic photographers for capturing the rare northern lights seen all the way down in Georgia this week.

Aurora Pictures: Rare Northern Lights Seen in U.S. South

According to National Geographic:
"Auroras are created when charged solar particles collide with molecules in Earth's atmosphere, infusing the molecules with extra energy that then gets emitted as light.
Familiar green auroras appear lower in the atmosphere, around 60 miles (100 kilometers) above the surface. The light is actually a mix of colors, but the human eye is most attuned to the green part of the spectrum, according to the University of Alaska Fairbanks.
Sometimes, however, an influx of slower moving, less energetic particles can make auroras appear higher in the atmosphere, around 185 to 310 miles (300 to 500 kilometers). At these altitudes, the light displays are pure red."
