For over 150 years, the United States Nautical Almanac Office has published The Nautical Almanac, first as part of the American Ephemeris and Nautical Almanac and then on its own, to provide the U.S. Navy with a convenient form of the astronomical data used for celestial navigation. This book is still the standard resource for marine celestial navigation for the U.S. Navy.
The book contains the following data tabulated at hourly intervals to a precision of 0.1 arcminute: the Greenwich hour angle and declination of the Sun, Moon, and navigational planets; the Greenwich hour angle of Aries; positions of the navigational stars; rise and set times of the Sun and Moon for a range of latitudes; and other data. Each edition also contains a sight reduction table, sight reduction formulas, and various correction tables for sight reduction. There is a useful, concise sight reduction form at the back of the book.
The book is produced in collaboration with His Majesty’s Nautical Almanac Office in the UK.
“Essential for practical navigation at sea, companies unwilling to provide hardcopy Almanac’s.”
“This Nautical almanac performed as expected. In fact, it was overwhelming.”
“All the data you need is here!”
This book is a “Mini” (half the size of a piece of paper).
A popular size to carry anywhere (briefcase, large pocket, purse) but the print is large enough for easy reading. The binding is with coil, allowing easy flipping of pages without jamming.
The color covers are laminated for weather protection with black and white inside printing.
(A BIG size version (8 1/2 inch by 11 inch, the same size as a regular sheet of paper) is on this website too)
