APOD: 2022 October 10 - A Double Lunar Analemma over Turkey

Good morning, Rallypoint, and welcome to the October 10th edition of Astronomy Picture of the Day (APOD): "A Double Lunar Analemma over Turkey." You may recall that the typical analemma image we see on APOD is a solar analemma, released to coincide with spring/fall equinox or summer/winter solstice. Here, we see a lunar analemma produced over the course of two months. What's the difference? With a solar analemma, the results are produced by a single camera at one location at the same time (and it takes a year). A lunar analemma also needs a single camera and one location, but you wait 50 minutes and 29 seconds each day before capturing the next exposure. At the end of the month, the analemma emerges from the composite photograph.

Visit the APOD page itself and mouse over the image to see the dates as our Moon cycles through two successive orbits of Earth.
