A solar analemma is a diagram or graph that shows the sun’s position in the sky over the course of a year as seen from a single location on Earth. It’s caused by the Earth’s tilt and its elliptical orbit around the sun. The analemma looks like a slightly oblong figure 8, with one loop wider than the other.
Here are some things to know about the solar analemma:
Shape
The analemma’s shape varies depending on the time of day and the location on Earth. For example, analemmas viewed from different latitudes have different shapes.
Pattern
The sun appears at its highest point in the sky and in the analemma during summer, and at its lowest point in winter.
Equation of Time
The analemma also shows the Equation of Time, which indicates whether a clock is ahead or behind the sun.
The word “analemma” comes from the Ancient Greek word analēmma, which means “support”.
