Book Description

This is the ninth edition of this publication which presents in tabular and graphical form astronomical data required for the planning of activities, in particular aircraft movements, where the amount of daylight, the duration of twilight, and the position and phase of the Moon are important. This annual volume contains data for the times of rising and setting of the Sun and Moon, as well as the twilight times for latitudes between N72 degrees and S60 degrees. Graphical methods for determining this information at altitudes of up to 60,000 feet and at high latitudes are also provided, as are standard times for many places around the world.
