 For the past three months I have had a small pinhole solargraph camera mounted at GNTO facing west. It's been exposing the small piece of photo paper inside non-stop since the summer solstice when the sun was at it's most northern track (at the far right) until now (the last track on the left). During sunny days the track left behind is bright and unbroken, partly cloudy days show the track broken, and cloudy days show the track as almost non existent. At a glance you can see that in the past three months, GNTO has had about an equal amount of Sun and clouds. You can also see that yesterday, the last track on the left was interrupted by me stopping the exposure since the track ends at a point high in the curved arc.
