Northern Lights dancing in the sky over a wind farm in North Dakota this past weekend. This event was caused by a Kp-5 geomagnetic solar storm which resulted in many #NorthernLights sightings in the United States and Canada. The Northern Lights, also known as the Aurora Borealis, is a natural light caused by the collision of energetic charged particles with atoms in the Thermosphere. Photo by Mike Theiss @ExtremeNature
