How do you find out when a solar storm is?
I honestly don’t know.
But what I have read indicates that it has to do with solar flares, and we are currently in some sort of super-minimum.
During large solar flares, the Aroura Borialis is visible as far south as Chicago - without the flares, only for Santa to see.
But I can remark, that on a freezing cold night, somewhere above the artic circle, when the entire sky lights up with that beautiful blue-green light - you will forget that your e-tool just exploded in your hand.
All I could think about, is how this must be proof of God, and he was teaching us a lesson in humility. It is like standing on the Mountains for the first time, and being awed by the vista. Or seeing Phantom of the Opera - you either get it, or you never will.
Unlike when you are stuck in a Panamanian jungle, and a howler monkey poops in his hand and throws it at you - you have other thoughts, I assure you. That is quite a different experience.
