The Northern Lights are fascinating, reminding us that we are on a ball of rock spinning in space. I've seen them maybe twice in Seattle over the years.
We took a sub-Polar flight to Europe in the winter of 1986 and saw the Northern Lights for HOURS. It really was amazing. I have a window seat and my forehead kept getting cold from leaning on a window over the Arctic at 30,000 feet.
One the return flight, we went over Greenland in broad daylight and it was crystal clear, which is really rare. That was fantastic too, like another planet.
