This page calculates the altitude and azimuth of the Sun or Moon at multiple times
during any day between 1700 and 2100. Simply specify the **object**,
**date**, **tabular interval**, and **place**
below and click on the "Compute Table" button. The altitude and azimuth values are tabulated
as a function of the time of the place requested on a 24-hour clock.

Use Form A for cities or towns in the U.S. or its territories. Use Form B for all other locations. Both forms are immediately below.

Please read the Notes section for details on the data and definitions of altitude and azimuth.

### Form A - U.S. Cities or Towns

### Form B - Locations Worldwide

### Notes on the Data:

** Altitude** is the angle up from the horizon. Zero degrees altitude
means exactly on your local horizon, and 90 degrees is "straight up". Hence,
"directly underfoot" is -90 degrees altitude. Azimuth is the
angle along the horizon, with zero degrees corresponding to North, and
increasing in a clockwise fashion. Thus, 90 degrees is East, 180 degrees is
South, and 270 degrees is West. Using these two angles, one can describe the
apparent position of an object (such as the Sun at a given time).

The altitude and azimuth values are for the center of the apparent
disk of the Sun or Moon. The altitude values include the effect of
standard atmospheric refraction when the object is above the
horizon. The azimuth values are computed with respect to
** true north** (not magnetic).
For instructions on using a true azimuth (bearing) with a compass, see
NOAA's
Geomagnetism FAQs. To determine the magnetic declination for a
specific location and date, see
NOAA's
Geophysical Data Center - Magnetic Declination calculator.

A break in the output table indicates the object has dropped more than 12 degrees below the horizon and is not near the horizon again until the next indicated time.
