Sun Position (polar coordinates)
|
The observer is located at the centre of his "celestial sphere" with zenith Z above his head and the horizon N-E-S-W. The Sun, Moon or any other celestial body can be identified by the two coordinates altitude (elevation) h and azimuth az (horizontal coordinates). Altitude is the angular distance above the horizon (0 < h < 90°), and azimuth the angular distance, measured along the horizon, eastwards from the north point N in nautics (0 < alpha <360°), or westwards from the south point S (in astronomy).
