  HM Nautical Almanac Office - Wikipedia, the free encyclopedia
The HM Nautical Almanac Office (HMNAO), now part of the Rutherford Appleton Laboratory, near Abingdon in Oxfordshire, was established in 1832 on the site of the Royal Greenwich Observatory (RGO), where the Nautical Almanac had been published since 1767.
In 1937 it became part of RGO and moved with it, first to Herstmonceux, near Hailsham in East Sussex in 1948, then to Cambridge in 1980.

 Nautical almanac - Wikipedia, the free encyclopedia
A nautical almanac is a publication describing the positions and movements of celestial bodies, including the sun, moon, planets, and 57 stars chosen for their ease of identification and wide spacing.
The Almanac specifies for each whole hour of the year the position on the Earth's surface at which each body is directly overhead.
In Great Britain a nautical almanac has been published annually by the HM Nautical Almanac Office, ever since the first edition was published in 1767.

Astronomical data and various statistics are also found in almanacs, such as the times of the rising and setting of the sun and moon, eclipses, hours of full tide, stated festivals of churches, terms of courts, lists of all types, timelines, and more.
The precursor to the almanac was the Greek weather-calendar, the parapegma.
When almanacs were first devised, people still saw little difference between predicting the movements of the stars and tides, and predicting the future in the divination sense.

This value is currently used by the Nautical Almanac Office for all solar eclipse predictions [Fiala and Lukac, 1983] and is believed to be the best mean radius, averaging mountain peaks and low valleys along the Moon's rugged limb.
In general, the adoption of one single value for k is commendable because it eliminates the discontinuity in the case of annular-total eclipses and ends confusion arising from the use of two different values.
The Astronomical Almanac identified this event as a total eclipse of 3 seconds duration when in it was in fact a beaded annular eclipse.

In 1849, 50 years before the founding of the American Astronomical Society, the American Nautical Almanac Office was established in Cambridge, Massachusetts.
Under Simon Newcomb, Superintendent of the Office from 1877 until his retirement in 1897, a consistent system of constants was devised; some of these constants remained unchanged until 1984.
The American Nautical Almanac Office was dominated before World War II by its Directors William S. Eichelberger (1910-1929) and A. James Robertson (1929-1939).

Because of various lengths of the nautical mile in use throughout the world, due to differences in definition and the assumed size and shape of the earth, the International Hydrographic Bureau in 1929 proposed a standard length of 1852 meters, which is known as the international nautical mile.

From 1968 through 1980, the Nautical Almanac Office used two separate values for k in their predictions.
This value is now used by the Nautical Almanac Office for all solar eclipse predictions [Fiala and Lukac, 1983] and is currently the best mean radius, averaging mountain peaks and low valleys along the Moon's rugged limb.
Using the IAU value for k, the Astronomical Almanac identified this event as a total eclipse of 3 seconds duration when it was, in fact, a beaded annular eclipse.

 World War II American Air and Nautical Almanacs
US Naval Observatory for the duration of World War II to serve as Head Astronomer and Director of the USNO's Nautical Almanac Office, which produced the almanacs used for air and sea navigation.
When Eckert arrived and war was looming, there was a pressing need for rapid production of accurate and readable air almanacs for use by American flying forces; prior to this, only a couple air almanacs had been produced, and those by old-fashioned, slow, and error-prone manual methods.
The other major allies, Britain and the USSR, it seems, produced their own air and sea almanacs, rather than sharing, despite the hardships (Britain was bombed by Germany from 1940, and the USSR was invaded in 1941).

 Celestial Navigation - Reed's Nautical Ephemeris
Celestial navigation is based on spherical trigonometry and solving the “navigational triangle”—a theoretical triangle with the North or South Pole as one corner, the geographical position of the celestial body at another, and your assumed position as the third corner.
Reed’s Nautical Ephemeris includes the celestial navigation information necessary to calculate the position of a boat at sea using celestial navigation.
Our Nautical Ephemeris is the functional equivalent of the Nautical Almanac published annually by the United States Naval Observatory and Her Majesty's Nautical Almanac Office in the UK, but it is organized in quite a different and more compact fashion geared towards celestial navigation at sea.
