Author Description

The Almanac contains tabulations for the Sun, Moon, planets and stars, for use in the determination of position at sea from sextant observations. It also gives times of sunrise, sunset, twilights, moonrise and moonset, for use in the planning of observations; all necessary interpolation and altitude correction tables, the phases of the Moon; a pole-star table; diagrams and notes for the identification of stars and planets; information on eclipses of the Sun and Moon; and the standard times of most countries. To make the almanac self-contained, a set of concise sight reduction tables is included. Although designed for use at sea, this information is of value to anyone interested in astronomy.
