Abstract

An observer plotting the location of the Sun at noon over a year would notice it altering its position in two directions. It changes its elevation (angle above the horizon) and shiftseast and west of themeridian (line passing from northto south over the viewer’s head). These two displacements of the Sun in the sky produce a figure eight shape.

This paper investigates the causes of these observations and specific values are calculatedwiththeuseof simple algorithms.TheperspectiveisanEarth-centred view.
