Reference Chart for the Apparent Motions of the Sun, Moon and Planets

Abstract

THE apparent motions of the sun, the moon and the planets during the course of a year can be represented very conveniently by plotting on a single sheet of paper the right ascension of these bodies corresponding with each day of the year. The planetary chart prepared in this way gives a picture of the sky for the whole year, so far as the principal members of the solar system are concerned, and besides, it shows at a glance all the planetary phenomena and the days when they occur.
