Winter to Summer Solstice

For six months at a time, a small pinhole camera set out at our astronomy club’s observing site recorded the path of the sun.  You can see by the arcs on the image that we have a lot of sunny days around here.  Gaps in the solargraph indicate when the Sun was obscured by clouds.  This solargraph is a Winter to Summer Solstice record.
