Astronomical Almanac
An annual joint publication of the U.S. Naval Observatory (USNO) and (since the closure of the Royal Greenwich Observatory) the U.K. Nautical Almanac Office, which contains information on the positions of the Sun, the Moon, and the planets and their satellites, phases of the Moon, eclipses, sunset and sunrise, bright stars, and locations of observatories. It began in 1980 through the merger of The American Ephemeris and Nautical Almanac, produced by the USNO between 1855 and 1980, and The Astronomical Ephemeris, which originated in Britain in 1766 as The Nautical Almanac and Astronomical Ephemeris.
