This small, useful booklet contains general interest material preprinted from The Astronomical Almanac. It is published jointly by the U.S. Naval Observatory and Her Majesty's Nautical Almanac Office two years in advance of its date. It includes such things as: - dates for Solar equinoxes, solstices, phases of the Moon - eclipse maps - dates for various planetary phenomena - visibility and magnitudes of the planets - dates for some religious and civil holidays - chronological eras and cycles - the equation of time and declination of the Sun - sunrise/set, moonrise/set times - the position of Polaris.
Prepared jointly with Her Majesty's Nautical Almanac Office, United Kingdom Hydrographic Office. Designed in consultation with other astronomers of many countries. Provides current, accurate astronomical data for use in the making and reduction of observations and for general purposes. The Astronomical Almanac Online extends the printed version by providing data best presented in machine-readable form. Online data are provided for several years. Contains data for astronomy, space sciences, geodesy, surveying, navigation, and other applications. 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.

The Fifty Year Almanac of Astronomical Events: 2021 to 2070 is a catalog listing a wide range of solar system phenomena as seen from Earth. Each year gives a concise compendium of the most conspicuous and/or significant astronomical events involving the Sun, Moon and the planets. The astronomical events include the following. - solar and lunar eclipses - phases of the Moon - apogees and perigees of the Moon - Equinoxes and Solstices of Earth - aphelion and perihelion (Earth, Mars, Jupiter, Saturn and Uranus) - oppositions and conjunctions of the planets - elongations of Mercury and Venus - close conjunctions of the Moon with the planets and bright stars - close conjunctions of planets with bright stars and other planets - peak of major meteor showers The date and time of each event is given in Greenwich Mean Time (= Coordinated Universal Time). With 200+ events each year, the Fifty Year Almanac includes over 10,200 astronomical events.

This year the Almanac is bilingual, with the intention of promoting a dialog within the international community. In fact, because its distribution is exclusively through the web, it was necessary to meld the two versions, Italian and English, into one document. The format of the charts has remained the same as well as the contents, with some broadening and graphic improvements. The great events are detailed for the major cities of the world. Over 300 pages covers events in great detail, with orderly data in easy to read charts for a wide variety of phenomenon. Exhaustive data contained in this Almanac is designed to satisfy the needs of anyone that observes the sky whether professional or amateur. Included are phenomena that will be visible to the naked eye and those notable for their spectacularity and rarity. Besides the classical ephemerides of Sun, planets and Moon, there is data about conjunctions of every type, between planets, with the Moon, with the comets...
