Explanation: If you took a picture of the Sun at the same time each day, would it remain in the same position? The answer is no, and the shape traced out by the
Sun over the course of a year is called an
analemma. The Sun's apparent shift is caused by the
Earth's motion around the Sun when combined with the
tilt of the Earth's rotation axis. The Sun will appear at its highest point of the
analemma during
summer and at its lowest during winter.
Analemmas created from different Earth
latitudes would appear at least slightly different, as well as
analemmas created at a different time each day. The
analemma pictured to the left was built up by
Sun photographs taken from 1998 August through 1999 August from
Ukraine. The foreground picture from the same location was taken during the early evening in 1999 July.
