Also used for navigation by air and water.The Astronomical Almanac is a joint publication of the U.S. Nautical Almanac Office, United States Naval Observatory (USNO), in the United States and Her Majesty's Nautical Almanac Office (HMNAO), United Kingdom Hydrographic Office (UKHO), in the United Kingdom. This annual publication contains precise ephemerides of the Sun, Moon, planets, and satellites, data for eclipses and other astronomical phenomena for a given year, and serves as a world-wide standard for such information.

Written by a former freelance writer for Astronomy magazine, the guide provides almost daily data and information on the Moon and planets and lists details of hundreds of astronomical events. Included in the guide are: * Graphical depictions of the Moon and planets throughout the month * Data tables for the Moon and planets including position, magnitude, apparent diameter and elongation from the Sun. * Conjunctions between the Moon, planets and bright stars (including angular separations for planetary conjunctions.) * Lunar and Solar eclipses * Annual summaries of when to observe the planets * Annual summaries of notable close planetary conjunctions * Peak dates for the major meteor showers with moon phase * Inferior and superior conjunctions for Mercury and Venus * Greatest eastern and western elongations for Mercury and Venus * Oppositions and solar conjunctions for the outer planets * Dates of the equinoxes and solstices PLUS * Twenty-four star charts with accompanying lists of suggested deep sky objects Whether you're an expert astronomer or a casual star gazer, the almanac is the essential guide for observers everywhere. Praise for previous editions: "For a guy like me, that is always out observing and shooting the stars with my telescope, this book is VERY informative. Lots of great info. I will definitely refer to it before I go out with my scope. Thanks." - Peter Guierra, September 21st 2014 (Amazon US) "Love it! In the last few years my interest in astronomy has grown tremendously. This book will definitely come in handy." - Michael Dylo, October 26th 2014 (Amazon US) "I can't imagine how much work it took to bring together all the information in this book! With that said, it will be my constant observing companion observing for the next few years!" - WJohnson, September 20th 2014 (Amazon US) "This is a superb book, well laid out and easy to follow even if you are a complete novice or keen astronomer." - Mr Fletcher, October 26th 2014 (Amazon UK) "I found this book very user friendly and instinctive, it is exactly what I have been looking for." - K. J. Simmill, November 3rd 2014 (Amazon UK) "Very concise guide to the sky over the next few years, written with more advanced amateurs in mind, but could be used by anyone with more then a passing interest." - Amazon Customer, November 11th 2014 (Amazon UK)

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, part of the U.K. Hydrographic Office. 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 table; 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.

Designed for astronomers worldwide, the almanac provides details of thousands of astronomical events from 2016 through to the end of 2020. Written by a former freelance writer for Astronomy magazine, the guide includes almost daily data and information on the Moon and planets, as well as Pluto, Ceres, Pallas, Juno and Vesta: * The phases of the Moon * Conjunctions between the Moon, planets and asteroids (including angular separation for conjunctions involving the planets and asteroids.) * Lunar and Solar eclipses * Annual summaries of when to observe the planets and asteroids * Annual summaries of notable close planetary conjunctions * Peak dates for the major meteor showers with moon phase * Dates of perihelion, aphelion, perigee and apogee for the planets and asteroids * Inferior and Superior conjunction for Mercury and Venus * Greatest Eastern and Western elongation for Mercury and Venus * Opposition and solar conjunction dates for the outer planets and asteroids * Apparent diameter changes for the planets * Magnitude changes for the planets and asteroids * Constellation changes for the Sun, planets and asteroids * Dates of the equinoxes and solstices Whether you're an expert astronomer or a casual star gazer, the almanac is the essential guide for observers everywhere. (The first edition, detailing 2015-2019, has been downloaded nearly 6,000 times and has sold hundreds of paperback copies.
