Can you share a photo?
If you're interested in a real time video, here's one I captured a few weeks ago from our "back yard" (excuse the Instagram link)

Sadly we have pretty high winds at the moment and visibility is poor due to all the blowing snow, but if you're high up (eg an observation deck), it's a bit clearer.
It doesn't do what we saw justice at all.
Here's a color enhanced version of grafelic's photo that shows the color bands more easily,

Added some blur after color adjustments to remove pixelation artifacts.
Near, but definitely not retrospective
