From the explanation
“An analemma is that figure-8 curve that you get when you mark the position of the Sun at the same time each day throughout planet Earth’s year . In this case, a composite of 17 individual images taken at 0231 UT on dates between April 2 and September 16 follows half the analemma curve.”
