The dancing lights in the image above are the aurora borealis, viewed from the ground looking up. The aurora shown above occurred as the result of a CME that struck Earth’s magnetic field early on March 17, 2013. This week’s auroras are the result of a high-speed solar wind stream flowing from a coronal hole. Once it arrives, a high-speed solar wind stream effects the magnetosphere similar to CME, often creating auroras.
