Start by going downtown to the steps of the County Courthouse on Main Street and look northeast toward the JMS building. On the corner of the JMS rooftop you can see the flagpole.
When I revisited the corner flagpole up on the roof, the cans were still affixed with duct tape. The solargraph cans had been in place from July 12 (http://www.nightwise.org/single-post/2016/07/12/Historic-Sites-Launch-Legacy-Project) to October 28, 2016.
One can had a dimple in its side and one can had soggy paper (not sure if they were the same can).
The original solargraph from one can exhibited sepia colors, and was upside down and backwards. Flip the image so it's right side up...
Then invert the colors and flip it horizontally to get correct aspect. Notice the gap in the sun on the lower left portion. Apparently a piece of construction equipment obstructed the sun in those latter weeks. Yet for the time when the solar arc was not obstructed, before the equipment eclipsed the sun, enough light had already entered the can to build up the faint horizon.
