 | About VelaTerra A world clock that is much more than a clock! Besides showing local times, VelaTerra displays the current level of natural light (bright daylight, three levels of twilight, and night), moon information, and the national flag. Users can choose from over 500 cities in over 200 countries. Users may also define and add cities of their own choosing. VelaTerra is able to graphically display sun and moon rise and set times, three kinds of twilight, and detailed moon information (phase, tilt angle, position in the sky). The graphical displays of this information are very user configurable and allow easy visual comparisons between different cities. Users immediately gain a better sense of time and daylight hours for cities both faraway and nearby. The moon image in VelaTerra accurately displays the tilt angle of the moon’s crescent. Because this angle can change dramatically within the span of an hour, it is updated once a minute. Many more features. |
