Thee scale is what the pictures don't capture. The color is stronger in the camera but at some point there was a red or pink streak across half the sky. From zenith and down 1/2 way on one side and 2/3 on the other side. As usual, it's hard for a camera to capture the feeling of being there and having it all above you.
The scale of change I saw yesterday is that it fades in or changes over five seconds maybe, it's not changing faster than that. The most intense lights were over some 20 minute period maybe and then slowly it was mostly disappearing again.
