: a plot or graph of the position of the sun in the sky at a certain time of day (as noon) at one locale measured throughout the year that has the shape of a figure 8; also : a scale (as on a globe or sundial) based on such a plot that shows the sun's position for each day of the year or that allows local mean time to be determined
— an·a·lem·mat·ic adjective
Latin, sundial on a pedestal, from Greek analēmma, lofty structure, sundial, from analambanein to take up, restore, from ana- + lambanein to take
First Known Use: 1832
The analemma is the pattern the sun makes in the sky if you photograph it at the same time every day for a year. The figure eight is due to the tilt of the Earth's axis and its elliptical orbit around the sun.
