The Edmonton Journal reports that there were spectacular northern lights visible in the Edmonton sky one night last week. (Usually, you see northern lights in the winter but they can actually occur at any time of the year if atmospheric conditions are right). Viewing the aurora borealis is one of the great privileges of living in a northern country. Even though I know there's a rational scientific explanation for them, seeing this incredible natural phenomenon always produces great spiritual awe in me.
Over the years, I've most commonly seen northern lights in the form of great sheets of white light that move slowly and majestically in the dark heavens, fading and growing stronger by turns. On a couple of occasions I've seen huge sheets of green northern lights. I've never seen any other colours, although some people have been so blessed. Nor have I ever been lucky enough to "hear" the northern lights -- apparently, if conditions are sufficiently extreme, you can actually hear the aurora borealis make a tinkling sound as they move about the sky, much like ice cubes clinking together in a glass.
