I simply had to share this amazing clip of a proton are over Norway with you!
As you can see, a proton arc is a rare type of aurora. These are caused by protons bombarding our atmosphere, not by the electrons, which cause the more well-known Northern Lights.
If you’re interested in these, there is an excellent article about what Northern Lights are and What Causes them here.
Keep an eye on the sky, my furiends!
