amazing! does aurora borealis look that stunning for the naked eye?

Yes, when the aurora is powerful, this is what it looks like with the naked eye.
The energy of the aurora is measured in something called the "Kp index", where the most powerful aurora occurances can score maximum Kp 9. Last night the maximum Kp index was around 6.
