The Lunar Analemma
Robert Quimby, a professor of Astronomy at San Diego State University has used images from the east-facing HPWREN camera at the Mount Laguna Observatory to show how the Moon's position in the sky changes as it moves through its orbit. A plot showing the apparent position of the Moon every 24 hours and 50 minutes for 1 month is called the Lunar Analemma.
