Auroras and Star Trails over Iceland

This picture appealed to me because it is complex and unique. This picture looks colorful and unique. The picture contains what looks to be rocks on a lake. There are green auroras present in the sky as well as a trail of stars in the sky. The comments underneath the picture indicate that these are auroras and star trails. The location of this picture is in Ireland. The comments state that this is one of the quietest nights for auroras, and that the photograph is actually a three hundred and sixty degree view. Four wide angle cameras were used to capture this picture. The comments end with stating that the star trails were caused by the long exposure and Earth's rotation.
