One of the most active displays of aurora I've seen occurred directly overhead that night as seen in Highwood Saskatchewan after 2AM on April 11th, 2015. I lowered the tripod and kneeled in a ridiculous position to get this angle with the top of the tree and the aurora overhead. It appears to be a dove about to land on the tree top.
