UTM zones are numbered 1 through 60, starting at the international date line, longitude 180Â°, and proceeding east. Zone 1 extends from 180Â° W to 174Â° W and is centered on 177Â° W. Each zone is divided into horizontal bands spanning 8 degrees of latitude.
There are a couple of popular ways of specifying the location of a celestial object. The first is what you would probably use to point out a star to your friend: the altitude-azimuth system. The altitude of a star is how many degrees above the horizon it is (anywhere from 0 to 90 degrees). The azimuth of a star is how many degrees along the horizon it is and corresponds to the compass direction. Azimuth starts from exactly North = 0 degrees azimuth and increases clockwise: exactly East = 90 degrees, exactly South = 180 degrees, exactly West = 270 degrees, and exactly North = 360 degrees = 0 degrees.
