On a pair off of occasions I've seen endless sheets of green northern lights. I've never seen any other colours, time some terrain concede been so blessed. Nor concede I ever been lucky tolerable to "fall prey to" the northern lights -- evidently, if background are ample abundant, you can actually fall prey to the "aurora borealis" make a tinkling properly as they move about the sky, a lot for instance ice cubes clinking together in a window.
