Essential for celestial navigation, with tables for the Sun, Moon, planets, and stars.

The Nautical Almanac is a vital reference for celestial navigation, carried on every ship within the Royal Navy and widely used on sea-going vessels around the world. It is a core resource for navigational training and is required under Regulation 19.2.1.4 of SOLAS Chapter V in either paper or digital format.

This annual publication includes:

Tabulations of the Sun, Moon, navigational planets, and stars for celestial positioning.
Times of sunrise, sunset, twilights, moonrise, and moonset, plus lunar phases and eclipses.
Interpolation and altitude correction tables, pole star tables, and star identification aids.
Information on standard times for countries worldwide.
A concise set of sight reduction tables and sight reduction forms.
A six-page supplement on polar astronomical phenomena, requested by the Royal Navy.

Published jointly by the UK Hydrographic Office (UKHO) and the United States Naval Observatory, this authoritative guide remains essential for traditional and emergency celestial navigation.
