This is not a time-lapse. Photographer Kwon O Chul shows what aurora borealis looks like in real-time in this jaw-dropping video filmed in Yellowknife, Canada. What an incredible phenomenon to experience in-person. Video was shot on a Nikon D4, at ISO 6400, 24mm f/1.4G lens at f/2.0 or f/1.4.

An aurora (astralis in the south and borealis in the north) is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). The charged particles originate in the magnetosphere and solar wind and, on Earth, are directed by the Earth’s magnetic field into the atmosphere. [source]
