Army Ephemeris 1993 - 1997 (Fm 6-300) Department of the Army

This manual, ?Army Ephemeris ? 1993 -1997,? is a compilation of tables and charts which are used in field computations of astronomical observations by the field artillery. These tables and charts are used for computing azimuth of the Sun or selected stars by either the altitude or Artillery Astronomic Observation method. Special tables, which are tabular methods of computing Polaris, are included for a rapid computation of a Polaris azimuth. Tables and charts are also included to correct astronomic azimuth to grid azimuth and to extend azimuth by simultaneous observation. These table and charts are compiled and provide by the Astronomical Applications Department, US Naval Observatory H. M. Nautical Almanac Office, Royal Greenwich Observatory, and National Oceanic Atmospheric Administration.
