Moon Azimuth (when used with Moon Elevation) is an angular coordinate system for locating the moon’s positions in the sky. Azimuth is measured clockwise from true north to the point on the horizon directly below the moon. Elevation is measured vertically from that point on the horizon up to the moon. If you know the azimuth of the moon is 135° from north, and the elevation is 30°, you can look toward the southeast, about a third of the way up from the horizon to locate the moon. Because our planet rotates, azimuth and elevation numbers for the moon constantly changing with time and with the observer’s location on earth. A negative Moon Elevation places the moon’s location below the horizon.
