I think the large light circles you can see all over the image below was caused by light entering the rear viewer from the room behind me. All of the photos were taken looking towards Frobisher Bay. The bright white glow are apartments and the North Mart. The details will be a bit blurry because the camera was hand held.
You may notice in the photo below a dark line cutting across the northern lights. The line is a shadow caused by the exhaust of a passing airplane. When I noticed the line developing in earlier photos I thought something was wrong with the camera.
Note: My apologizes to anyone who may have looked up at the 5th floor of the Frobisher Hotel and seen a half naked, hairy, bit overweight fellow hanging out of the window. Okay maybe not that hairy.
