3. Position of the Sun - Wikipedia

   en.wikipedia.org/wiki/Position_of_the_Sun

   To find the Sun's position for a given location at a given time, one may therefore proceed in three steps as follows: [1] [2] calculate the Sun's position in the ecliptic coordinate system, convert to the equatorial coordinate system, and; convert to the horizontal coordinate system, for the observer's local time and location.

4. Shadows (software) - Wikipedia

   en.wikipedia.org/wiki/Shadows_(software)

   Shadows is a software package for the calculation and drawing of sundials and astrolabes, available as a freeware in its base level.. It has been developed by François Blateyron, software developer and amateur astronomer, who made it available on Internet since 1997 and continues to improve it. [1]

5. Burt's solar compass - Wikipedia

   en.wikipedia.org/wiki/Burt's_solar_compass

   Burt's solar compass or astronomical compass/sun compass is a surveying instrument that makes use of the Sun's direction instead of magnetism. William Austin Burt invented his solar compass in 1835. The solar compass works on the principle that the direction to the Sun at a specified time can be calculated if the position of the observer on the ...

6. Declination - Wikipedia

   en.wikipedia.org/wiki/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. The declination angle is measured north (positive) or south (negative) of the celestial equator , along the hour circle passing through the point in question.

7. Sun path - Wikipedia

   en.wikipedia.org/wiki/Sun_path

   Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.

8. Analemmatic sundial - Wikipedia

   en.wikipedia.org/wiki/Analemmatic_sundial

   The declination of the sun (determines the daily gnomon position). Analemmatic sundials are sometimes designed with a human as the gnomon. In this case the size of the hour marker ellipse is constrained by human height and the latitude of the sundial location, since the human gnomon shadow must fall on the hour marker ellipse to accurately ...

9. Solar azimuth angle - Wikipedia

   en.wikipedia.org/wiki/Solar_azimuth_angle

   The solar azimuth angle is the azimuth (horizontal angle with respect to north) of the Sun's position. [1] [2] [3] This horizontal coordinate defines the Sun's relative direction along the local horizon, whereas the solar zenith angle (or its complementary angle solar elevation) defines the Sun's apparent altitude.
