Azimuth [Astro*Index]The primary angle of the Horizon system of coordinates. Measured along the Horizon eastward from the north point, to the vertical circle containing a body.

♦ Elevation ♦ Horizontal Coordinate System ♦ Celestial Coordinates ♦ North Point ♦ Altitude ♦ Horizon ♦ Vertical Circle
The first of the two coordinates of the horizonal system of celestial coordinates (the other coordinate is altitude). Azimuth is measured eastward from the north point of the horizon to the vertical circle (90° to the horizon) that runs through the planet or point to be measured.

♦ Elevation ♦ Horizontal Coordinate System ♦ Celestial Coordinates ♦ North Point ♦ Altitude ♦ Horizon ♦ Vertical Circle
A direction of angular measurement, in the plane of thehorizon, from the (compass') direction of (true) NORTH eastward to the hour circle of the body.

♦ Elevation ♦ Horizontal Coordinate System ♦ Celestial Coordinates ♦ North Point ♦ Altitude ♦ Horizon ♦ Vertical Circle
A point of the horizon and a circle extending to it from the zenith; or an arc of the horizon measured clockwise between the south-point of the horizon and a vertical circle passing through the center of any object.

♦ Elevation ♦ Horizontal Coordinate System ♦ Celestial Coordinates ♦ North Point ♦ Altitude ♦ Horizon ♦ Vertical Circle
That angle in the Horizon system of co-ordinatesmeasured from the observers meridian to a specified vertical circle. It is labeled with the prefix "N" (North) or "S" (South)', and the suffix "E" (East') or "W" (West).

♦ Horizon ♦ Coordinate System ♦ Vertical Circle
A map projection of the surface of the earth centered at a chosen point in such a way that a line drawn from that point to any other point represents the shortest distance between those two points. The lines can be drawn to scale.
