It's that uneven figure 8 that can be found on globes in a deserted part of the Pacific, a shape known as an analemma. |
If he had taken the photographs at an earlier time in the day, the analemma would have been tilted to the left. |
An analemma is the figure-eight pattern formed by plotting the position of the sun in the sky every day at the same time for a year. |
The analemma also records the difference between local solar time and local mean time for each day of the year. |
As the length of daylight is influenced by the position of the sun and the axis of the earth, this is easily seen on the Geochron analemma. |
The height of the analemma is due to the tilt of the Earth, and its width is due to both the tilt and the elliptical nature of Earth's orbit. |
