USNO API Demo App

The United States Naval Observatory Astronomy Applications Data Services are being converted to APIs. This app makes use of the available APIs to provide: images of some of the planets and moons in the solar system, maps of daylight on the Earth at a particular date and time, lists of upcoming lunar phases, sunrise/sunset and moon rise/set/phase information for locations in the United States (by name) and international locations (by coordinates).

Current available APIs:
- Complete Sun and Moon Data for One Day
- Lunar Phases
- Day and Night Across the Earth
- Apparent Disk of a Solar System Body

NOTE: This is not an official USNO application!!!
