A scale of the sun's declination for each day of the year, drawn across the torrid zone on an artificial terrestrial globe.
A characteristic figure eight diagram that arises when one plots the Equation of Time versus the declination of the sun. An analemma for Bloomington, Indiana is shown in figure .
a tool found on the globe that shows at what degree latitude the direct rays of the Sun are striking the Earth on a particular date.
A graduated scale shaped like a figure 8 and showing the sun's declination and the equation of time for each day of the year usually constituting part of a sundial.
a figure-eight pattern formed by mapping the shadow of a fixed object everyday at the same time over the course of a full year
The analemma "shows the distance that the vertical ray of the sun is from the equator for every day in the year." (Denoyer 87). The analemma can appear as an elongated "0" or "a figure 8". The figure 8 analemma also shows "the difference between mean solar time and sundial time" (Denoyer 87).For more information on the analemma, see "Analemma Dilemma" in the "Books and Articles about Globes" page.
The lemniscate-shaped form that results from plotting the position of the Sun at the same time every day.
The analemma is a figure-8-shaped diagram that shows the declination of the sun (the angle that the sun is from the equator), for each day in the year. If you took a snapshot of the sun at the same time each day (from the same location), the Sun would make a figure shaped like an analemma during the course of a year (this is because the Earth is tilted on its axis and because it doesn't orbit the Sun in a perfect circle).
The analemma is a figure 8-shaped diagram that shows the declination of the sun for each day in the year. If you took a snapshot of the the sun at the same time each day and from the same location, it would form this shape.
If you take a picture of the Sun at the same time each week, from exactly the same position, on a single frame of film, the figure of eight shape that results is called the analemma. See www.analemma.de for more detail and photos.
