Auroras Across Canada 

The dancing lights in the video are the aurora borealis or Northern Lights. These auroras are at their most dynamic during geomagnetic storms—often the result of solar storms called coronal mass ejections, or CMEs, that originate from the sun. The aurora shown above occurred as the result of a CME that erupted from the sun early on Mar. 15, 2013. Some 46 hours later, early on Mar. 17, 2013, this CME struck Earth’s magnetic field, depositing and storing energy in Earth’s magnetosphere. When this energy was released, charged particles from the magnetosphere were sent rushing down towards Earth’s atmosphere where they collided with neutral particles, creating the brilliant aurora.
