Here's a Norwegian "Northern-light picture of the month" page:
http://www.northern-lights.no/zope//Contest/Gallery/
The above link takes you to the photos of the current month, but
you can choose to view a lot of photos from prior months as well.
You'll probably notice that northern-lights comes in a great
variety of "shapes" and colours.
