Set your location

Needed to work out what is above you. It stays in this browser: the calculation runs here, and there is no server on this site to send it to.

Elevation is the angle above your horizon; azimuth is the compass bearing to look. An object being above the horizon does not make it visible: most are too faint to see without optics, and the ones that are visible need darkness at your position and sunlight on the satellite.
