GeoClock Tour - Basic Features

This screen shot shows the main features of GeoClock. The main window shows a map of the Earth (many maps are available) with the current sun and moon positions. The moon phase is ilustrated, and the map is highlighted to show the sunlight (bright) and twilight (half-toned) and dark areas. In addition, various cities are marked, and their current local times are indicated (this later feature is only available on registered versions of GeoClock). The up and down arrows (see Tokyo, for example) indicate that the day in that city is ahead or behind the reference city. At the bottom is a legend. The top line of the full legend shows current moon position, phase (in percent illumination, with the arrow indicating waxing or waning), azimuth and elevation from a user selected city, and moon rise and set times. The middle line names the selected city, and gives the current sun rise and set times, and sun azimuth and elevation from the selected city. The bottom line gives the sun position (the coordinates of the point where the sun appears directly overhead) and the current date and time in that city.
