3 Introduction This Nautical Almanac contains the Ephemerides of the "First Point of Aries" and sixty selected stars. It is designed for determination of Position (geographical Latitude and Longitude) from astronomical observations (Altitude of Celestial Objects). The data compiled in this Nautical Almanac is based on calculations done with the software package "NOVAS" from the U.S. Naval Observatory ( fundamental star data was originally obtained from the "Bright Star Catalogue" (5th revised edition of 91). However, this data has recently been updated from other star catalogues. The complete star data as used in this Almanac is shown on the next page. For the astrodynamical calculations, the following values for "delta T" (the difference between terrestrial time realized by atomic clocks and defined by the irregular rotation of the Earth) have been used: Jan : 68.1 s Feb : 68.1 s Mar : 68.2 s Apr : 68.2 s May: 68.2 s Jun : 68.2 s Jul : 68.3 s Aug: 68.3 s Sep: 68.4 s Oct : 68.4 s Nov: 68.5 s Dec: 68.5 s Blank Page NOTICE: This Nautical Almanac uses a slightly different approach for the interpolation of the integral-hour values of Greenwhich Hour Angle and Declination, compared to the techniques used in most commercially available Almanacs.

On each of the maps, the stars used in this Almanac are labeled with their traditional names. The first two maps are stereographic maps of the stars of the northern- and southern hemisphere, respectively. These maps are centered on the celestial poles and may be used for observations at locations in high northern- or southern latitudes. The following eight maps show the star constellations on the local hemisphere for locations on the Equator. These maps can be used for observations at locations in lower latitudes.

The stars are plotted with their Altitude (Hc) and Azimuth (Az) coordinates. The Azimuth scale is plotted on the circle of 0 -Altitude (local horizon). The Azimuth is the approximate compass direction in which the star is visible. Each of these maps is valid for a location on the equator at a specific time of the day.

The circle of constant declination is shown at (Celestial Equator). The Sidereal Hour Angle of a specific star can be directly read from the SHA scale plotted on the Celestial Equator, while, the Declination can be determined by transferring the distance from the star to the center of the map onto the separate Declination scale. The Sidereal Hour Angle is zero for the "First-Point-of-Aries" and increases westward. The map is centered on the celestial south pole and shows the brightest stars (up to magnitude 4.5) of the southern celestial hemisphere. The circle of constant declination is shown at (Celestial Equator). The Sidereal Hour Angle of a specific star can be directly read from the SHA scale plotted on the Celestial Equator, while, the Declination can be determined by transferring the distance from the star to the center of the map onto the separate Declination scale.
