- Altitude and Azimuth
Two coordinates specifications suffice to locate an object visible in the night sky: its altitude above the horizon and its azimuth (location on the circle of the horizon).

- Latitude and Longitude
Any location on Earth is described by two numbers--its latitude and its longitude. If a pilot or a ship's captain wants to specify position on a map, these are the coordinates they would use.

- Right Ascension and Declination
Right Ascension (abbreviated R.A.) and Declination (abbreviated Dec) are a system of coordinates used by astronomers to keep track of where stars and galaxies are in the sky. They are similar to the system of "longitude" and "latitude" used on the Earth.

- Sun or Moon Altitude/Azimuth Table
This page provides a way for you to obtain a table of the altitude and azimuth of the Sun or Moon during a specific day, at a time interval that you specify. 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 standard time of the place requested (daylight time is not used) on a 24-hour clock. This form is provided by the USNO.
