Five solargraphs in the the Saint Pius X bell tower yielded new images of the solar arc, shown below paired approximately with cell phone Pano images.

After scanning the black and white photographic paper, resulting images include the original, the adjusted, the panorama, and the paired. Thanks to Doreen Sandroni and Betsy Quinn for mou
