1. Analemma

   In astronomy, an analemma is a curve representing the changing angular offset of a celestial body from its mean position on the celestial sphere as viewed from another celestial body. The term is used when the observed body appears, as seen from the viewing body, to move in a way that is repeated at regular intervals, such as once a year or once a day. The analemma is then a closed curve, which does not change. Because of the Earth's annual revolution around the Sun in an orbit that is elliptical and tilted relative to the plane of the equator, an observer at a fixed point on the Earth sees the Sun appear to move in an analemma around a mean position, taking a year to do so. The mean position appears to revolve around the Earth once every mean solar day, because of the Earth's rotation. This daily revolution is not considered to be averaged out to get the mean. The mean position of the Sun is therefore at the same place in the sky at the same time every day, but not at other times. Therefore if the observed position of the Sun in the sky is plotted or photographed at the same time every day, or every few days, for a year, the points trace out the analemma.

1. analemma

   A projection of the sphere on the plane of the meridian, taken in a lateral point of view, so that the colours become circles, whilst those whose planes pass through the eye become right lines, and the oblique circles ellipses. On globes it is represented by a narrow double-looped formed figure, the length of which is equal to the breadth of the torrid zone, and is divided into months and days, to show approximately the solar declination and the equation of time.
