The Northern Lights

My little guy was up in the middle of the night last night (again!) and since it was a clear night I thought it was worth a look... and there they were. This is the third time I have seen the northern lights since living up here... there were none last year, that I noticed. This fall has been trying to make up for it though. Still no colours other than the bluish green, but last night was a big, unmistakable swath of them up in the sky. The one thing I have noticed with them is that they don't sway, as I expected them to, they shift. One moment it will be shaped like 'this' and the next moment, it is shaped slightly different... but you don't see it changing. I showed Allan before putting him back to bed, but he had the same reaction as Maria had... "Oh... can I go back to bed?"
