A Great Wall of Color is what was revealed in this 10 second exposure photo…even though my eyes were only showing the bright section of Green above the trees, its often when the Aurora suddenly gets dims to the eye you should be ready, sometimes there is a lot more going on that only the camera can pick up!!!
