Latest days the earth has been hit by an unusually strong solar storm. Which has made it possible to see the northern lights as south as France for example. Right now the KP level is at 5, which is unusually high. But it can raise to even higher levels at any time, yesterday I saw it was up at 8-9. Just have to wait until it gets dark
