Abstract:

The Shang dynasty ruled China for more than two centuries during the period from -1500 to -1000. A number of observations of lunar eclipses that have been preserved from the Shang dynasty may be the oldest astronomical observations known that involve the moon. The dating of these eclipses would supply valuable data for determining the secular accelerations within the sun-earth-moon system. This report presents a canon of all lunar eclipses that occurred between -1500 and -1000 for use in the dating of the Shang eclipses. The canon includes the circumstances needed to determine the visibility of each eclipse at any point on earth. Author
