Difference between Azimuth and Position of the Sun

Azimuth vs. Position of the Sun

An azimuth (from the directions) is the horizontal angle from a cardinal direction, most commonly north, in a local or observer-centric spherical coordinate system. The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth's surface.

Astronomy

Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos.

Celestial equator

The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth.

Declination

In astronomy, declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle.

Horizontal coordinate system

The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system: altitude and azimuth.

Latitude

In geography, latitude is a coordinate that specifies the north–south position of a point on the surface of the Earth or another celestial body.

Meridian (astronomy)

In astronomy, the meridian is the great circle passing through the celestial poles, as well as the zenith and nadir of an observer's location.

Right ascension

Right ascension (abbreviated RA; symbol) is the angular distance of a particular point measured eastward along the celestial equator from the Sun at the March equinox to the (hour circle of the) point in question above the Earth.

Spheroid

A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters.
