Philip R Luoma Anderson installed the cameras on Sept 22 and retrieved them on Dec 19 from the roof of Birch Grove Elementary School for the Arts ‑ 4690 Brookdale Drive, Brooklyn Park, MN  55443. The cameras were looking due South over the roof of the school.  In the foreground you see the roof, ventilation pipes on the roof, then some trees, and the sky with the sun passing through it.

Here are two solargraphs from Brooklyn. Look at them side by side so we can follow the Sun´s paths forward how the curves are continuing.
