Azimuth and Elevation Applet More details: Sun Shadow Applet Sun Azimuth at Rise and Set Applet Elevation and Azimuth Applet Applet: Azimuth, Latitude, Hour Angle, Declination   Diagrams of the elevation and the azimuth of the Sun for various latitudes and dates (exinoxes and solstices), generated by this applet Select your location from the menu list, or enter the coordinates (decimal degrees) for the latitude, and press RETURN, and for the longitude, and press RETURN:      In the azimuth diagram the red part of the curve indicates that the sun is above horizon, in case of blue the sun has set:   Choose from the menu to get different diagrams, tables, and charts.

Choose AZ/ELEV Chart from the menu

The Graph below helps estimate source rising and setting.
It is a plot of elevation vs. azimuth, with lines of constant hour angle (red) and declination (blue) indicated. The lines of constant declinations are plotted in increments of 10 degrees, while the lines of constant hour angle are plotted in increments of 1 hour.

Example for 52.5°N:

Declination of the Sun 20°, sunrise (elevation 0°) is about 8 hours before noon at an azimuth angle of about 55°.

Choose Table from the menu to get this data window: Choose Get Time from the menu to compute the time for a given azimuth angle:   The azimuth and elevation angle are the coordinates of the observer's local horizontal system: the azimuth is the angular distance measured along the horizon (in nautics 0°=N, 90°= E, 180°=S, 270°= W), the elevation is the angular distance measured above the horizon. For a location of latitude beta the elevation angle of the sun at local noon is: elev. angle = 90° - beta + declin where declin is the declination angle of the sun. Example: beta= 50° North delta=23.5° on June 21: elev. angle = 90° - 50° + 23.5° = 63.5° delta=-23.5° on Dec. 21: elev. angle = 90° - 50° - 23.5° = 16.5°       Please visit my: GeoAstro Applet Collection Web Li Sun path chart program (University of Oregon) SunPosition Calculator The Sundial Primer   Last Modified: 2010, Aug 27
