## Altitude and Azimuth CalculatorMoon and Sun altitude and azimuth, and the phase of the Moon calculatorThe dates and times used by the calulator are consistently UTC. Look for the maximum solar altitude around noon local time. The azimuth plot will show the Sun due South (or North if you live "down under"). Sunrise and sunset are when the Sun crosses altitude 0. ## for new jersey:To get local time in NJ, subtract 5 hours from UTC in the winter, 4 in the summer. Noon local time will then be 17:00 or 16:00 UTC.## Special CasesTry to generate the following plots.A A A A A The last two plots strain the server -- please use sparingly! ## NotesI verified the numbers produced by this program using those of the U.S. Naval Observatory. Here is a comparison table for Jan 1, 2000. The errors, when there are any, are very small. (The USNO does not provide the negative altitudes).## Referencesaltaz.cpp. Source code for the calculator.How to compute planetary positions. Exceptionally clear, concise and useful.
