This is a complete copy of the official government edition. This book lists the "locations" of the sun, moon, stars, and planets for every day, hour, minute, and second of the year. Location, as used here, means the latitude (called declination) and longitude (called Greenwich Hour Angle) of the point on earth that is directly below these objects in the sky — this point is called the Geographic Position of the object. The almanac also includes several other tables needed for the practice of celestial navigation.

The Almanac is needed for the actual practice celestial navigation, but you do not need this to work the home study course on celestial navigation. In the home study course table sections are provided.

The Almanac is published once a year and it is most convenient to use an up to date copy. However, you can use an old copy for the sun and stars, with some corrections which are all explained in the book. For moon and planets, you must have a current edition.

If your cel nav application is mainly a back up and not intended to be used daily, then we do also carry two long term products. We offer the Starpath Perpetual Almanac that is valid from 1752 to 2100 that covers all bodies as a PC software program and we offer a printed Long Term Almanac for sun and stars, which also includes a set of sight reduction tables.

The main reference for the content of the Nautical Almanac is the US Naval Observatory. The USNO includes a web site that will compute the almanac data on line for any specific object, time, and date within the current year. See the Starpath Celestial Resources section for a list of services and see specifically the beautiful Celestial Navigation Data page. The Nautical Almanac is actually a joint publication of USNO and the British counterpart called Her Majesty's Nautical Almanac Office. We try to keep all of these frequently-changing reference links up to date in the Resources sections.

The almanac is an annual publication. The volume for the following year is usually available sometime between September and October. Once available, we stock both the present year and the next, 200X and 200X+1. Last year, the new edition was available in late July.

Thus sometime around July, please tell us in the Comments section at the last step of the order which year you want. Till then we have only the current year.
