For over 150 years the United States Nautical Almanac Office has published The Nautical Almanac, first as part of the American Ephemeris and Nautical Almanac, and then on its own, to provide the US Navy with a convenient form of the astronomical data used for celestial navigation. This book is still the standard resource for marine celestial navigation for the U.S. Navy. The book is produced in collaboration with Her Majesty's Nautical Almanac Office in the UK. That Office maintains the copyright on the material it produces. The Nautical Almanac contains the following data tabulated at hourly intervals to a precision of 0.1 arcminute: the Greenwich hour angle and declination of the Sun, Moon, and navigational planets; the Greenwich hour angle of Aries; positions of the navigational stars; rise and set times of the Sun and Moon for a range of latitudes; and other data. Each edition also contains a sight reduction tab≤ sight reduction formulas; and various correction tables for sight reduction. There is a useful concise sight reduction form at the back of the book. The Nautical Almanac is available several months in advance of its edition date.

The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.

This famous set of mathematical tables was first published in 1803. It has been a bestseller ever since, and despite developments in electronic navigation it remains an essential requirement for anyone learning and practising astro-navigation. Last updated in 1994, the editor, George Blance, has worked for some time on the modernisation of all the tables for this major new edition. New tables have been included and obsolete ones deleted to conform with the changing techniques of navigation, with the aim of improving the accuracy of the calculated position and reducing the tedium of the calculation. All the tables required for coastal and deep sea navigation are included. A simple uniform method of interpolation for all the trigonometrical tables is used. Certain tables and data are also included which are not readily available on board ship or are only used in the examination room. The section 'Seaports of the World' has also been extensively updated and restructured with several hundred additional ports. The ports are listed geographically in the following order from Arctic Russia, Scandinavia, the Baltic Sea, the Atlantic coast of Europe, the Mediterranean Sea, West Africa, East Africa, Arabia, the Persian Gulf, the Indian sub-continent, the Far East, Australasia, the west coast of North and South America and finally the east coast of North and South America. At the back of the section is an index of the seaports.

On Celestial Wings

In November 1940, 44 young military cadets graduated from the first Army Air Corps Navigational Class at Miami University in Coral Gables, Florida. The cadets came from all parts of the United States-from the urban areas of the East Coast, westward to the Appalachian Mountains, to the Midwest and prairie states, to the Rocky Mountains, and the West Coast. These young men came from the inner cities, the farmlands, the mountains, and coastal regions, and they were all volunteers. Most were college-educated and in the prime of life. World War II was raging in Europe and it was becoming increasingly difficult for the United States to remain neutral. A few farsighted men in our small Army Air Corps saw the essential requirement for trained celestial navigators in our military aircraft. The instructor for this navigational class was a 34-year-old high school dropout by the name of Charles J. Lunn. Charlie Lunn had first learned the art of celestial navigation aboard freighter ships in the Caribbean and later as the navigator aboard Pan American Airline planes flying to Europe and Asia. This book was written by one of those young navigators, Edgar D. Whitcomb, from Hayden, Indiana. Ed Whitcomb tells about these young comrades-in-arms and draws vivid word portraits of them as we learn of their assignments to Air Corps units. We learn how they survived and how some died in World War II. We learn about Ed's own pre-Pearl Harbor assignment with the 19th Bombardment Group at Clark Field in the Philippines and the unfortunate, and perhaps inexcusable, decision not to deploy our B-17 Flying Fortress bombers immediately after the attack on Pearl Harbor resulting in the loss of 40 percent of thoseaircraft as they sat parked at Clark Field when the Japanese destroyed that vital military air base on the afternoon of 8 December 1941.
