Taken at Fuertes Observatory with a point and shoot (15 second exposure). Notice the streak on the bottom of the picture… I actually thought that I had gotten a satellite when I first saw the photograph on my computer, which got me really excited for a while. Some thought convinced me that it most likely is a plane, and we can get a rather good measure of the frequency of the blips from its lights by a simple calculation which I leave as an exercise for the reader.
