The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory
captions and links exemplifying features within the Earth system. The
community is invited to contribute digital imagery, short captions and
relevant links.


 Southern England Solargraph: Solstice to Solstice

   Summary Authors:  Greg Parker;  Jim Foster

   Shown above is a  pinhole camera’s view of the  path of the Sun,
   from  solstice to solstice, captured from my location in the
    south of England. The resulting trace is called a solargraph. The
   topmost bright line here is the Sun's path on the date of the Summer
   Solstice (June 21, 2022), and the very lowest bright line is the Sun's
   path on date of the Winter Solstice (December 21, 2021). Note that the
   dark striping translates to cloudy days -- times my observatories
   (bottom of photo) got very little use. Remarkable here, though, is the
   wide band of bright lines in late winter -- fine days to be outdoors
   during the daytime and to set up my scopes at night. Compare this view
   to that from  2015.

   Photo details: For the first time since I’ve worked on these
   solargraphs, I used color -- Ilford Multigrade IV RC De Luxe 8 x
   10-inch photographic paper.
