The northern lights brightened and really came to life as we watched. Then one of the bands of green light began creeping south in our direction weaving a little -like a snake-. It was fantastic viewing as it came nearer our location, then the end of it was above us. The end formed a back to front question mark directly above us, the streaks of light radiating down from this point were dancing in the moonlight. What a fantastic moment to share. Thank you mother nature!
