We use altitude and azimuth to describe the location of an object in the sky as viewed from a particular location at a particular time. ... The altitude is the distance an object appears to be above the horizon. The angle is measured up from the closest point on the horizon.

The altitude and azimuth readouts on the Hyakutake view provide a more precise readout than just degrees. They also provide the sub-degree incrments of minutes (') and seconds ("). For finding Hyakutake, this extra precision is unneeded, so just ignore it.

The second coordinate is the altitude of the object. Since stars and other celestial objects are not on the surface of the Earth, we wish to measure how far above the surface they ... Click "OK." This will place the altitude and azimuth grid lines on the screen. Now place the mouse cursor over the "N" on the horizon.

Important Note: the azimuth on the celestial sphere model is marked incorrectly: azimuth should be to the North, to the East, to the South, and to the West. The altitude is the angular distance of an object above (or below) the horizon plane defined by the horizon ring.

Use the Altitude and Azimuth controls to position the guide over a star and note the corresponding angles. You may also type in values for Altitude and Azimuth and have the computer orient the guide for you.

I have just received a GeoClock program that runs on my PC. It graphically shows the position of the sun and gives figures for Azimuth and Elevation. I'm confused about what Azimuth and Elevation mean in reference to plotting the sun's course across the sky. ... How do you calculate the azimuth and altitude of an object?

A Java applet to calculate the Sun position in terms of azimuth and altitude for a given time and location. ... Azimuth The direction angle of Sun in the horizontal coordinate system. Zero azimuth corresponds to Sun position in North, 90 o corresponds to Sun in East, 180 o corresponds to Sun in South and 270 o corresponds...

The altitude of an object is its angular distance from the horizon, and the azimuth is generally defined as its angular distance from due south, measured eastward. To calculate the approximate altitude and azimuth for an object, then, you need to estimate those angular distances.
