Analemma is the figure “8” loop that results when one observes the position of the sun at the same time of day over the course of a year. The 23.5° tilt of the earth’s axis of rotation and its elliptical orbit about the sun result in the apparent change in the sun’s location in the sky when observed at the same location at the same time of day over a year’s time.
For this image the photos are all made during the local noon. The highest point shows the sun near the day of Summer Solstice (June 21) and the lowest marks the shortest days near the Winter Solstice (Dec. 21).
