Mesa Solargraph
This image is a three month solargraph from Anderson Mesa. I collaborated with Brian Skiff at Lowell Observatory and the above is our result.
I made a small pinhole camera loaded with photo paper, and then Brian placed the camera and let it collect solar photons for a while. A long while.
This is the result from the Autumn Equinox until Winter Solstice. The streaks in the image were made by the daily track of the Sun.
