Navigating by the Moon, Planets, and Stars

The Nautical Almanac is one of the longest-running publications in the Federal Government, dating back to 1852. It’s also one of the most distinctive-looking books I’ve ever seen.  The covers are orange and made of a stiff board-like material, and the cover graphics certainly look like they date back to 1852. Between those covers lie the complex mathematical tables that, “along with the chronometer, the sextant, a steady hand and a keen eye, are the resources needed to navigate by the stars.” Honestly, the contents mean less than nothing to a non-math person, but what images they conjure up for a history person! Old salts striding across a ship’s deck, sextant in hand, getting ready to round the Horn – well, you get the idea.

The Almanac is a unique example of a Government publication produced by two countries – the United States Naval Observatory (USNO) and Her Majesty’s Nautical Almanac Office (HNMAO). Also unique is that the U.S. part of the Almanac is in the public domain, but the British part is under Crown Copyright.

The Nautical Almanac is one of a number of almanacs published by the U.S. Naval Observatory: the Astronomical Almanac, the Air Almanac, and Astronomical Phenomena. Together, they provide a corpus of navigational knowledge that spans the centuries but is still the ultimate backup to the GPS technology of today.

I wonder if they’ll ever change those orange covers?

    Astronomical Phenomena is the book I am going to order. The price (international) is not high, that’s good. I hope it’s written with not so complicated language – English is not my native and the topic sounds great for me. I hope I will be able to read it 🙂

      Marek: According to the Naval Observatory, which publishes it, “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. “

    The must for anybody who uses a telescope to find optional sources of scientific entertainment and learing from the lens of a telescope to the lens of a microscope…

    Tired of seeing a child becoming hooked upon narcotics to only see them only sleep it off in the dog house…?

    This publication just might spark their interest in “learning” and not “burning” the church down…

    Wow, thanks for the instant reaction! Just click on any of the titles and it will take you to a page on GPO’s online bookstore where you can order the book.

    Note: These books are all basically tables of numbers, so they’re not really something for kids. A teenager with some math backgound might be able to use them.
