Last night’s aurora event is being described by many as the most spectacular of this solar cycle, resulting from a severe geomagnetic storm (G4 intensity) as a coronal mass ejection from the sun hit the upper atmosphere.
New photos of the event continue to pour in from around the world at the SpaceWeather.com aurora photo gallery, which is running very slow right now.
Here are a handful of the photos posted there. Note the wide range of colors.
