Driveway Analemma
EXPLANATION
Does the Sun return to the same spot on the sky every day? No. A more visual answer is an analemma, a composite of sky images taken at the same time and from the same place over a year. At completion, you can see that the Sun makes a figure 8 on the sky. The featured unusual analemma does not, however, picture the Sun directly: it was created by looking in the opposite direction. All that was required was noting where the shadow of an edge of a house was in the driveway every clear day at the same time. Starting in March in Falcon, Colorado, USA, the photographer methodically marked the shadow’s 1 pm location. In one frame you can even see the photographer himself. Although this analemma will be completed in 2025, you can start drawing your own driveway analemma—using no fancy equipment—as soon as today.
