A book containing all current data: navigational, tidal, astronomical and so on. It is published annually.
An annual publication of the U.S. Naval Observatory and H. M. Nautical Almanac Office, Royal Greenwich Observatory, listing the Greenwich hour angle and declination of various celestial bodies to a precision of 0.1 minute of arc at hourly intervals; time of sunrise, sunset, moonrise, moonset; and other astronomical information useful to navigators. Prior to 1960 separate publications were issued by the two observatories entitled the American Nautical Almanac and the Abridged Nautical Almanac. See American Ephemeris and Nautical Almanac.
A nautical guide, published yearly, which contains information about the positions of celestial bodies around the Earth at certain times, and is used to aid in celestial navigation; all time information in the Almanac is noted in Greenwich Mean Time (GMT)
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. The Sun, Moon and Planets 'move' independently and so are specified separately, but for the stars only Aries is specified, the other stars having a set angular distance from that.
Nautical Almanac are a noise music group with a rotating membership based around Carly Ptak and Twig Harper, originating from the Michigan scene which produced Wolf Eyes, Beast People, Andrew W.K. and his alter ego Steev Mike. Influenced by Harry Pussy and Caroliner, among others, Nautical Almanac began as a costumed noise duo in Chicago before relocating to Baltimore, Maryland in 2001, where they founded the Here See record label and now defunct Tarantula Hill performance venue.
