In England, the first Nautical Almanac and Astronomical Ephemeris was published for the year 1767 by the Astronomer Royal, Nevil Maskelyne, from the Royal Greenwich Observatory. This was the first almanac ever to contain data dedicated to the convenient determination of longitude at sea.
Sextant readings require adjustments for atmospheric refraction, dip (height of eye above sea level), and semi-diameter (for the sun and moon). The 2008 almanac includes dedicated correction tables for the Sun, stars, planets, and Moon to convert your raw sextant altitude ( ) into true altitude ( Step-by-Step: How to Use the 2008 Almanac Data
Is this for , a specific training course workbook , or checking an old ship log ?
This measurement dictates the angular distance westward from the Greenwich Meridian to the celestial body's celestial meridian. nautical almanac 2008 pdf
This shift was a major event for the navigation community. While it made the almanac more "portable" in a digital sense, it was a sharp departure for sailors accustomed to a sturdy, waterproof book on their bridge table.
Specialized data for finding latitude quickly using the North Star.
Contains the Greenwich Hour Angle (GHA) and Declination (Dec) for the planets (Venus, Mars, Jupiter, Saturn) and the 57 navigational stars. In England, the first Nautical Almanac and Astronomical
: It is an excellent tool for students learning "sight reduction." Using an older almanac allows learners to practice with real data without needing a current year's physical copy for every exercise.
