Obviously there was time lapse used and the video quality was above what you'd get with your phone or a standard camera. There was likely some editing done as well but most of the images I saw are pretty representative of what you might see under optimal conditions because they are often more muted or limited in their intensity but at other times, they're intense and beautiful beyond description.
The aspect you can't duplicate in video or photos is the surrounding visuals. The light display may be limited in scope at times but what's going on in your peripheral vision does make a difference, even if it's just a jet black sky.
Here's an article that may be of interest to some from 'The Aurora Zone' on the actual process involved:
The Aurora Borealis originates some 93,000,000 miles away on the surface of the Sun with a massive explosion of electromagnetic matter called a Coronal Mass Ejection (CME). CMEâs usually emanate from the more active areas of the Sunâs surface and they throw a stream of electronically charged solar particles known as Solar Wind into the vastness of space. It is when these particles are directed towards the Earth that we can see the Northern Lights three or four nights later.
As the Solar Wind approaches the Earth it causes a distortion in our magnetic field and, whilst most of the particles are deflected away from us, some escape into our atmosphere around the magnetic poles. At this point, the âescapedâ particles collide with the atoms and molecules that form the gases in our atmosphere and cause them to become âexcitedâ. This is a complicated business but essentially, when an âexcitedâ atom or molecule begins to calm or return to its original state, it emits photon energy in the form of light.
It is the emissions of these photons on a huge scale that causes the Aurora to appear in our night sky.
