This six month Solargraph from Anderson Mesa says it all.

Placed in collaboration with Brian Skiff of Lowell Observatory from Winter Solstice 2008 to Summer Solstice 2009.

This solargraph is the result of 2.5 days in the Sun at Fort McKavett.

I set two homemade solargraph “cameras” out on the field near the flagpole and let them expose from 2 PM Thursday afternoon, until Saturday night.

The sun left its path as a blotchy (it was cloudy, thus the blotches) streak on the right side of the image above.

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.
