Sun Traces Huge Figure-8 Patterns in Sky

Here is an intriguing time-lapsed photo of the sun’s position in the sky over Wroclaw, Poland, taken three-times a day throughout one year:


Maciej Zapiór, a solar physicist at the University of the Balearic Islands in Palma, Majorca, and colleague Lukasz Fajfrowski built a pinhole camera and set it to make 1-minute-long exposures onto a single piece of photographic paper at 10:30, 12:00 and 13:30 each day from 1 March 2013 to 1 March 2014.  The resulting image shows how the position of the sun in the sky changes throughout the year.  In the summer it is higher, in the winter lower.  Its position also shifts horizontally, tracing a figure-of-eight path called an analemma.
